Background: Integrin alpha 4/CD49d

The alpha 4 subunit, also known as CD49d and VLA-4 alpha subunit, forms heterodimers with Integrin beta 1 (CD29) or beta 7. Integrins alpha 4 beta 1 and alpha 4 beta 7 are receptors for fibronectin and VCAM. Integrin alpha 4 beta 1 also binds the mucosal addressin cell adhesion molecule (MAdCAM-1).
