UniProt functional annotation for A4D1P6



	UniProt functional annotation for A4D1P6

UniProt code: A4D1P6.

Organism: Homo sapiens (Human).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

Function: Functions as a negative regulator of the PI3 kinase/PI3K activity associated with endosomal membranes via BECN1, a core subunit of the PI3K complex. By modifying the phosphatidylinositol 3- phosphate/PtdInsP3 content of endosomal membranes may regulate endosome fusion, recycling, sorting and early to late endosome transport (PubMed:26783301). It is for instance, required for the delivery of cargos like BST2/tetherin from early to late endosome and thereby participates indirectly to their degradation by the lysosome (PubMed:27126989). May play a role in meiosis (By similarity). {ECO:0000250|UniProtKB:Q7TMQ7, ECO:0000269|PubMed:26783301, ECO:0000269|PubMed:27126989}.

Subunit: Interacts with WDR81; involved in early to late endosome cargo transport (PubMed:26783301, PubMed:27126989). Interacts with BECN1; negatively regulates the PI3 kinase/PI3K activity associated with endosomal membranes (PubMed:26783301). {ECO:0000269|PubMed:26783301, ECO:0000269|PubMed:27126989}.

Subcellular location: Early endosome membrane {ECO:0000269|PubMed:26783301}; Peripheral membrane protein {ECO:0000269|PubMed:26783301}. Late endosome membrane {ECO:0000269|PubMed:26783301, ECO:0000269|PubMed:28404643}.

Similarity: Belongs to the WD repeat WDR91 family. {ECO:0000305}.

Sequence caution: Sequence=AAF29021.1; Type=Frameshift; Evidence={ECO:0000305};
