Summary

ITGA10 (integrin subunit alpha 10, HGNC:6135) is a protein-coding gene on chromosome 1q21.1, encoding Integrin alpha-10 (O75578). Integrin alpha-10/beta-1 is a receptor for collagen.

Integrins are integral transmembrane glycoproteins composed of noncovalently linked alpha and beta chains. They participate in cell adhesion as well as cell-surface mediated signalling. This gene encodes an integrin alpha chain and is expressed at high levels in chondrocytes, where it is transcriptionally regulated by AP-2epsilon and Ets-1. The protein encoded by this gene binds to collagen. Alternative splicing results in multiple transcript variants.
