Yes. USP46 rescue experiments require attention to complex partner requirements: • Construct design: use a codon-modified USP46 sequence with a C-terminal tag (FLAG, HA). USP46 is small (~366 amino acids) and tolerates either N- or C-terminal tagging. • Catalytically-dead rescue: an active site cysteine mutation (typically C44A) serves as the deubiquitinase specificity control. • WDR48/WDR20 partner considerations: USP46 functions as part of a ternary complex with WDR48 and WDR20. Rescue interpretation should account for WDR partner availability — overexpressed USP46 without partners may show reduced activity. • Functional readout: rescue should restore deubiquitination of substrates including PHLPP and AMPA receptor subunits, as measured by cycloheximide chase and ubiquitination Western blots. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on the experimental question. The Knockout line is appropriate for asking whether USP38 is required for its reported functions in TBK1 regulation, innate immune signaling, or histone H2BK120 deubiquitination. Overexpression is useful for testing whether elevated USP38 is sufficient to dampen innate immune responses or alter chromatin modification patterns. For USP38 research, the EDITGENE Knockout line in HAP1 is particularly valuable for innate immunity studies where partial substrate stabilization in diploid lines can obscure phenotypes. Rescue with wild-type or catalytically-dead USP38 is essential for distinguishing deubiquitinase activity from scaffolding functions, particularly given USP38's reported roles in protein complex assembly.

Primary applications: • Innate immune signaling: type I IFN reporter assays, ISG induction, and TBK1 activation analysis following viral mimic stimulation (poly(I:C), STING agonists). • Histone modification: ChIP-qPCR for H2BK120ub levels at specific genomic loci, and global Western blot analysis of histone ubiquitination. • Substrate ubiquitination: ubiquitin proteomics to identify substrate dependencies on USP38 deubiquitinase activity. • Transcriptional analysis: RNA-seq to map gene expression changes downstream of altered chromatin modification or innate immune signaling. EDITGENE recommends this model for researchers investigating USP38 biology, innate immune regulation, and chromatin deubiquitination.

Yes. USP38 rescue experiments require attention to innate immune context and histone modification activity: • Construct design: use a codon-modified USP38 sequence with a C-terminal tag (FLAG, HA). USP38 has reported nuclear localization for histone-related functions; tag choice should not disrupt nuclear targeting. • Catalytically-dead rescue: an active site cysteine mutation serves as the specificity control for distinguishing deubiquitinase from scaffolding functions. • Pathway-specific rescue interpretation: TBK1 regulation and H2BK120 deubiquitination may show different rescue kinetics — assess both readouts to distinguish substrate-specific phenotypes. • Functional readout: rescue should restore IFN signaling regulation and histone ubiquitination patterns. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on the experimental question. The Knockout line is appropriate for asking whether USP32 is required for its reported functions in Rab7 deubiquitination, endosomal trafficking, or cancer-associated growth phenotypes. Overexpression is useful for testing sufficiency, or for studying USP32 amplification effects observed in certain cancer contexts. For USP32 research, the EDITGENE Knockout line in HAP1 is the more direct tool for dissecting endogenous function — HAP1's clean genetic background and near-haploid copy number are particularly valuable for a DUB whose biology involves balanced ubiquitin-deubiquitin cycles on multiple substrates. Rescue with wild-type or catalytically-dead USP32 is the standard specificity control.

Primary applications: • Rab7 ubiquitination: Western blot and ubiquitin pull-down analysis of Rab7 ubiquitination status in the absence of USP32. • Endosomal trafficking: imaging-based analysis of late endosome morphology, EGF receptor trafficking, and lysosomal fusion dynamics. • Cancer phenotype assays: proliferation and tumor cell biology readouts relevant to USP32 amplification observed in certain cancer contexts. • Substrate identification: ubiquitin proteomics to expand the catalog of USP32 substrates beyond Rab7. EDITGENE recommends this model for researchers investigating USP32 biology, endosomal trafficking regulation, and cancer-relevant deubiquitination.

Yes. USP32 rescue experiments require attention to membrane localization and Rab7 substrate biology: • Construct design: use a codon-modified USP32 sequence with a C-terminal tag (FLAG, HA). USP32 contains EF-hand and DUSP domains that should be preserved; large N-terminal tags can interfere with substrate engagement. • Catalytically-dead rescue: active site cysteine mutation serves as the deubiquitinase specificity control. • Rab7 substrate engagement: rescue interpretation should include Rab7 ubiquitination state as a direct substrate readout, in addition to downstream endosomal trafficking phenotypes. • Functional readout: rescue should restore Rab7 deubiquitination and normal endosomal compartment morphology by imaging. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on the experimental question — though for USP31, this question has to come second to defining what those questions are. USP31 remains poorly characterized in the literature, and the Knockout line is most useful for unbiased discovery: identifying ubiquitination changes and pathways affected by USP31 loss without prior assumptions. Overexpression is more useful once candidate substrates are identified, allowing tests of sufficiency for deubiquitination. For initial characterization of USP31, the EDITGENE Knockout line in HAP1 is the higher-value starting point because emerging factors benefit particularly from clean loss-of-function genetics — the near-haploid background eliminates ambiguity from partial reduction effects. Discovery-oriented experiments (ubiquitin proteomics, transcriptomics) in the knockout are likely to be more informative than overexpression at this stage of characterization.

Primary applications: • Discovery ubiquitin proteomics: TUBE pull-down combined with mass spectrometry to identify proteins whose ubiquitination changes upon USP31 loss; foundational data for an under-characterized DUB. • Transcriptomic profiling: RNA-seq to identify downstream pathways affected by USP31 loss, generating testable hypotheses about its functional context. • NF-κB pathway studies: where preliminary data suggest USP31 involvement in NF-κB regulation, reporter assays and target gene expression analysis. • Substrate validation: candidate substrate identification followed by deubiquitination assays in vitro and in cells. EDITGENE recommends this model as a starting platform for functional characterization of USP31, an emerging factor in the USP deubiquitinase family.

Yes, and rescue experiments are particularly important for USP31 given its emerging status: • Construct design: use a codon-modified USP31 sequence with a C-terminal tag (FLAG, HA). For an under-characterized protein, both tag positions should be tested initially to confirm functional rescue. • Catalytically-dead rescue: an active site cysteine mutation is essential — for emerging factors, distinguishing deubiquitinase activity from non-catalytic functions is particularly important. • Discovery-oriented rescue: rescue with both wild-type and catalytically-dead constructs in parallel during phenotypic discovery experiments helps identify which phenotypes reflect USP31's enzymatic activity versus its potential scaffolding roles. • Functional readout: rescue should restore phenotypes identified in discovery transcriptomics or ubiquitin proteomics experiments. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on the experimental question. The Knockout line is appropriate for asking whether USP24 is required for its reported functions in p53/MDM2 axis regulation, DNA damage response, or autophagy-related deubiquitination. Overexpression is useful for testing whether elevated USP24 stabilizes specific substrates or for studying USP24 in cancer contexts. For USP24 research, the EDITGENE Knockout line in HAP1 is the more informative starting tool — USP24 has been implicated in multiple regulatory pathways with partial functional overlap, and complete loss in a near-haploid background reveals substrate dependencies that may be masked in diploid backgrounds. Rescue with wild-type or catalytically-dead USP24 is the standard approach for assigning observed effects to deubiquitinase activity.

Primary applications: • p53 stability and DDB2 ubiquitination: Western blot analysis of p53 protein levels and DDB2 ubiquitination state following USP24 loss. • DNA damage response: γH2AX dynamics, repair kinetics, and survival assays following UV irradiation or other DNA damaging agents. • Autophagy regulation: LC3 lipidation, p62 levels, and autophagy flux measurements to assess USP24's reported autophagy-related functions. • Cancer phenotype assays: proliferation and chemosensitivity studies relevant to USP24's reported roles in cancer biology. EDITGENE recommends this model for researchers investigating USP24 biology, p53 pathway regulation, and DNA damage response.

Yes. USP24 rescue experiments require attention to multiple substrate dependencies: • Construct design: USP24 is a large protein (~2,600 amino acids); use codon-modified sequences with C-terminal tags (FLAG, HA). Full-length cloning requires careful vector selection. • Catalytically-dead rescue: active site cysteine mutation serves as the deubiquitinase specificity control. • Multi-substrate rescue interpretation: USP24 has reported roles in p53 stability, DDB2 regulation, and autophagy — rescue effects on different substrates may show different kinetics and should be assessed independently. • Functional readout: rescue should restore substrate-specific deubiquitination patterns and downstream phenotypes (DNA damage response, autophagy flux). HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on the experimental question. The Knockout line is appropriate for asking whether USP19 is required for its reported functions in ER-associated protein quality control, HSP90 client stability, or unconventional secretion pathways. Overexpression is useful for testing whether elevated USP19 is sufficient to drive substrate stabilization or alter ER stress responses. For USP19 research, the EDITGENE Knockout line in HAP1 is the more rigorous starting tool because USP19's ER membrane localization and multifunctional domain architecture make precise functional dissection challenging — complete loss provides the cleanest baseline for mechanistic analysis. Rescue with wild-type, catalytically-dead, or domain-deletion USP19 constructs is essential for mapping function to specific structural elements.

Primary applications: • ER quality control: assessment of ERAD substrate stability and unfolded protein response activation in the absence of USP19. • HSP90 client stability: cycloheximide chase analysis for HSP90-dependent client proteins to assess USP19's role in client protein turnover. • Unconventional secretion: where relevant, analysis of misfolded cytosolic protein secretion via USP19-dependent unconventional pathways. • Domain-specific functions: rescue experiments with full-length, transmembrane-truncated, or catalytically-dead USP19 to map functional contributions of different protein regions. EDITGENE recommends this model for researchers investigating USP19 biology, ER-associated protein quality control, and HSP90 client regulation.
