Background: Integrin alpha 1/CD49a

Integrin alpha 1 (also VLA-1, CD49a and Laminin and Collagen Receptor) is a 190‑210 kDa member of the integrin alpha chain family of molecules. It is found on smooth muscle cells, osteoblasts, adipocytes and intestinal epithelium. Integrin  alpha 1 forms a noncovalent heterodimer with Integrin beta 1, and serves as a divalent-cation dependent receptor for collagen types I, IV, VI, XIII and XVI. It also binds the diarrhea-associated NSP4 enterotoxin of rotavirus. Mature human Integrin alpha 1 is a 1151 amino acid (aa) type I transmembrane glycoprotein that contains a 1113 aa extracellular domain (ECD) and a 15 aa cytoplasmic tail. The ECD contains one vWFA/I‑domain (aa 147‑360) that binds collagen, plus multiple divalent cation binding sites. Potential splice variants exist that show a two and four aa substitution for aa 765‑1179. Over aa 29‑1141 (the ECD), human Integrin  alpha 1 shares 88% aa identity with mouse Integrin  alpha 1.
