UniProt functional annotation for Q13042

UniProt code: Q13042.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: Component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C complex acts by mediating ubiquitination and subsequent degradation of target proteins: it mainly mediates the formation of 'Lys-11'-linked polyubiquitin chains and, to a lower extent, the formation of 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains. {ECO:0000269|PubMed:18485873}.
 
Pathway: Protein modification; protein ubiquitination.
Subunit: V-shaped homodimer. The mammalian APC/C is composed at least of 14 distinct subunits ANAPC1, ANAPC2, CDC27/APC3, ANAPC4, ANAPC5, CDC16/APC6, ANAPC7, CDC23/APC8, ANAPC10, ANAPC11, CDC26/APC12, ANAPC13, ANAPC15 and ANAPC16 that assemble into a complex of at least 19 chains with a combined molecular mass of around 1.2 MDa; APC/C interacts with FZR1 and FBXO5 (PubMed:26083744, PubMed:25043029). Interacts with PPP5C and CDC20 (PubMed:9628895, PubMed:9405394). Interacts with CDC26 (PubMed:19668213). {ECO:0000269|PubMed:19668213, ECO:0000269|PubMed:25043029, ECO:0000269|PubMed:26083744, ECO:0000269|PubMed:9405394, ECO:0000269|PubMed:9628895}.
Subcellular location: Cytoplasm, cytoskeleton, microtubule organizing center, centrosome {ECO:0000269|PubMed:7736578}. Cytoplasm, cytoskeleton, spindle {ECO:0000269|PubMed:7736578}. Note=Colocalizes with CDC27 to the centrosome at all stages of the cell cycle and to the mitotic spindle.
Domain: TPR repeats 1-7 mediate homodimerization, while the C-terminal TPR repeats bind to CDC26, burying its hydrophobic N-terminus. {ECO:0000269|PubMed:19668213}.
Ptm: Phosphorylated. Phosphorylation on Ser-560 occurs specifically during mitosis. {ECO:0000269|PubMed:14657031}.
Similarity: Belongs to the APC6/CDC16 family. {ECO:0000305}.
