an apoptosis inhibitor that is expressed during the G2/M phase of the cell cycle. Associates with the microtubules of the mitotic spindle and any disruption results in the loss of apoptosis activity. May play a role in neoplasia. Inhibitor of caspase-3 and caspase-7. Two splice variant isoforms have been described. Note: This description may include information from UniProtKB.
Molecular Function: caspase inhibitor activity; chaperone binding; cobalt ion binding; cofactor binding; cysteine protease inhibitor activity; enzyme binding; identical protein binding; metal ion binding; microtubule binding; protein binding; protein heterodimerization activity; protein homodimerization activity; Ran GTPase binding; tubulin binding; ubiquitin-protein ligase activity; zinc ion binding
Biological Process: cell division; cellular protein metabolic process; chromosome segregation; cytokinesis; establishment of chromosome localization; G2/M transition of mitotic cell cycle; mitosis; mitotic cell cycle; negative regulation of apoptosis; negative regulation of caspase activity; negative regulation of transcription, DNA-dependent; positive regulation of cell proliferation; positive regulation of exit from mitosis; positive regulation of mitotic cell cycle; post-translational protein modification; protein amino acid phosphorylation; protein complex localization; protein sumoylation; protein ubiquitination; regulation of signal transduction; small GTPase mediated signal transduction; spindle checkpoint; transcription, DNA-dependent
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
