Scientific Data

Western Blot Detection of Human Integrin a1/CD49a antibody by Western Blot. View Larger

Detection of Human Integrin alpha 1/CD49a by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF Membrane was probed with 2 µg/mL of Human Integrin a1/CD49a Monoclonal Antibody (Catalog # MAB5676) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Integrin a1/CD49a at approximately 190 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

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.
