The encoded protein is thought to help regulate the spindle assembly checkpoint by preventing early anaphase onset. This protein specifically deubiquitinates CDC20, which stabilizes the anaphase promoting complex/cyclosome. [provided by RefSeq, Dec 2016]. * **<color #00a2e8>UniProt Summary</color>**: Deubiquitinase that plays a key regulatory role in the spindle assembly checkpoint or mitotic checkpoint by preventing premature anaphase onset. Acts by specifically mediating deubiquitination of CDC20, a negative regulator of the anaphase promoting complex/cyclosome (APC/C). Deubiquitination of CDC20 leads to stabilize the MAD2L1-CDC20-APC/C ternary complex (also named mitotic checkpoint complex), thereby preventing premature activation of the APC/C. Promotes association of MAD2L1 with CDC20 and reinforces the spindle assembly checkpoint. Acts as a negative regulator of histone H2B (H2BK120ub1) ubiquitination. {ECO:0000269|PubMed:17443180, ECO:0000269|PubMed:22681888}. <button type='primary' size='sm' modal='Pfam_Domains'>Pfam Domains</button> <button type='primary' size='sm' modal='GO_terms'>GO Terms</button> <modal id='Pfam_Domains' size='lg' title='Pfam Domains'> |zf-UBP| |UCH| </modal> <modal id='GO_terms' size='lg' title='GO Terms'> |negative regulation of ubiquitin protein ligase activity| |regulation of mitotic spindle checkpoint| |regulation of spindle checkpoint| |regulation of mitotic cell cycle spindle assembly checkpoint| |negative regulation of ubiquitin-protein transferase activity| |regulation of ubiquitin protein ligase activity| |regulation of cell cycle checkpoint| |regulation of mitotic metaphase/anaphase transition| |regulation of ubiquitin-protein transferase activity| |regulation of metaphase/anaphase transition of cell cycle| |thiol-dependent ubiquitinyl hydrolase activity| |regulation of mitotic sister chromatid separation| |regulation of chromosome separation| |regulation of mitotic sister chromatid segregation| |negative regulation of protein ubiquitination| |regulation of sister chromatid segregation| |negative regulation of protein modification by small protein conjugation or removal| |regulation of chromosome segregation| |thiol-dependent ubiquitin-specific protease activity| |regulation of mitotic nuclear division| |regulation of nuclear division| |regulation of protein ubiquitination| |regulation of protein modification by small protein conjugation or removal| |chromosome segregation| |negative regulation of transferase activity| |protein deubiquitination| |protein modification by small protein removal| |proteasome-mediated ubiquitin-dependent protein catabolic process| |regulation of chromosome organization| |proteasomal protein catabolic process| |regulation of mitotic cell cycle phase transition| |regulation of cell cycle phase transition| |cell division| |ubiquitin-dependent protein catabolic process| |modification-dependent protein catabolic process| |modification-dependent macromolecule catabolic process| |proteolysis involved in cellular protein catabolic process| |negative regulation of protein modification process| |cellular protein catabolic process| |regulation of mitotic cell cycle| |protein catabolic process| |regulation of cell cycle process| |negative regulation of catalytic activity| |zinc ion binding| |cellular macromolecule catabolic process| |regulation of transferase activity| |protein modification by small protein conjugation or removal| |negative regulation of cellular protein metabolic process| |macromolecule catabolic process| |organonitrogen compound catabolic process| |negative regulation of protein metabolic process| |negative regulation of molecular function| |regulation of cell cycle| |proteolysis| |regulation of organelle organization| |cell cycle| |organic substance catabolic process| |cellular catabolic process| |regulation of protein modification process| </modal> \\ === CRISPR Data === <button type='primary' size='small' modal='Compound_Hit'>Compound Hit</button> <button type='default' size='small' modal='Most_Correlated_Genes'>Most Correlated Genes in Chemogenomics</button> <button type='primary' size='small' modal='Essential_Avana'>Tissues where Essential in the Avana Dataset (DepMap 20Q1)</button> <modal id='Compound_Hit' size='lg' title='Compound Hit'> ^Screen^Score^ |[[:results:exp122|Golgicide-A 4μM R03 exp122]]|2.03| </modal> <modal id='Most_Correlated_Genes' size='lg' title='Most Correlated Genes in Chemogenomics'> No correlation found to any other genes in chemogenomics. </modal> <modal id='Essential_Avana' size='lg' title='Tissues where Essential in the Avana Dataset (DepMap 20Q1)'> Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| </modal> == Essentiality in NALM6 == * **<color #00a2e8>Essentiality Rank</color>**: 4986 * **<color #00a2e8>Expression level (log2 read counts)</color>**: -1.2 <button type='primary' size='small' modal='Dist_expr'>Expression Distribution</button> <modal id='Dist_expr' size='lg' title='USP44 Expression in NALM6 Cells: -1.2'> {{:chemogenomics:nalm6 dist.png?nolink |}} </modal> Last modified: 2026/01/07 22:37by 127.0.0.1
