USP44 Gene (Protein Coding)

Ubiquitin Specific Peptidase 44

GC12M095516
GIFtS:
38
The protein encoded by this gene is a protease that functions as a deubiquitinating enzyme. 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] See more...

GeneCards Summary for USP44 Gene

USP44 (Ubiquitin Specific Peptidase 44) is a Protein Coding gene. Among its related pathways are Deubiquitination and Metabolism of proteins. Gene Ontology (GO) annotations related to this gene include cysteine-type endopeptidase activity and thiol-dependent ubiquitin-specific protease activity. An important paralog of this gene is USP49.

UniProtKB/Swiss-Prot Summary for USP44 Gene

  • 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.
