Ancient ubiquitous protein 1 is a protein that in humans is encoded by the AUP1 gene.{{cite journal | vauthors = Jang W, Weber JS, Bashir R, Bushby K, Meisler MH | title = Aup1, a novel gene on mouse chromosome 6 and human chromosome 2p13 | journal = Genomics | volume = 36 | issue = 2 | pages = 366–8 | date = Jan 1997 | pmid = 8812468 | doi = 10.1006/geno.1996.0477 }}{{cite journal | vauthors = Kato A, Kawamata N, Tamayose K, Egashira M, Miura R, Fujimura T, Murayama K, Oshimi K | title = Ancient ubiquitous protein 1 binds to the conserved membrane-proximal sequence of the cytoplasmic tail of the integrin alpha subunits that plays a crucial role in the inside-out signaling of alpha IIbbeta 3 | journal = J Biol Chem | volume = 277 | issue = 32 | pages = 28934–41 | date = Aug 2002 | pmid = 12042322 | doi = 10.1074/jbc.M204340200 | doi-access =free }}{{cite web | title = Entrez Gene: AUP1 ancient ubiquitous protein 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=550}}

Function

This gene encodes a protein that contains a domain with homology to the ancient conserved region of the archain 1 gene and a domain that may be involved in binding ubiquitin-conjugating enzymes. The protein encoded by this gene has been shown to bind to the conserved membrane-proximal sequence of the cytoplasmic tail of integrin alpha (IIb) subunits. These subunits play a crucial role in the integrin alpha (IIb) beta (3) inside-out signalling in platelets and megakaryocytes that leads to platelet aggregation and thrombus formation. This gene overlaps the gene for mitochondrial serine protease 25.

Interactions

AUP1 has been shown to interact with ITGA2B.
