|The integrin alpha 4 (also known as CD49d and ITGA4) belongs to the integrin alpha chain family of proteins. Integrins are heterodimeric integral membrane proteins composed of an alpha and beta chains. Alpha 4 chain associates with either beta 1 or beta 7 chain. It has been demonstrated that the putative ligand-binding sites of both integrin alpha 4 beta 1 and alpha 4 beta 7 is located on the alpha 4 chain. These ligands included Madcam, VCAM, and fibronectin. Madcam is known as the principal ligand for integrin alpha 4 beta 7. Recently it was also demonstrated that HIV-1 envelope can mimic Madcam by binding to and signaling though integrin alpha 4 beta 7, the gut mucosal homing receptor for peripheral T cells. Despite its predicted molecular weight, Integrin alpha 4 will often run at higher molecular weight in SDS-PAGE. At least two isoforms are known to exist. The immunogen to this antibody is within the Integrin alpha 4 recombinant protein fragment and thus will recognize it.|
