UniProt functional annotation for Q9H1A4



	UniProt functional annotation for Q9H1A4

UniProt code: Q9H1A4.

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: 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. {ECO:0000269|PubMed:25043029, ECO:0000269|PubMed:26083744}.

Ptm: Phosphorylated. Phosphorylation on Ser-355 occurs specifically during mitosis. {ECO:0000269|PubMed:14657031}.

Disease: Rothmund-Thomson syndrome 1 (RTS1) [MIM:618625]: An autosomal recessive disorder characterized by sparse hair, bilateral juvenile cataracts, and poikiloderma, a genodermatosis presenting with mottled pigmentation, telangiectasia and epidermal atrophy. Additional features are short stature, dystrophic and thin nails, and genital, skeletal and dental abnormalities. RTS1 is not associated with an increased risk of cancer. {ECO:0000269|PubMed:31303264}. Note=The disease is caused by variants affecting the gene represented in this entry.

Similarity: Belongs to the APC1 family. {ECO:0000305}.
