Rabbit anti Human CD49d polyclonal antibody
detects an epitope within the C-terminal region of human CD49d, also known as integrin alpha-4 or VLA-4 subunit alpha. CD49d is a ~150kDa single pass type 1 transmembrane glycoprotein with seven FG-GAP
repeats, characteristic of alpha integrins, in its extracellular domain. CD49d can be proteolytically cleaved to yield framents of 80 and 70 kDa (Hemler et al. 1987
). CD49d associates with either CD29
to form VLA-4 or with Integrin beta-7 to form The Peyer patches-specific homing receptor LPAM-1, involved in the lymphocyte migration and homing to gut-associated lymphoid tissue (Sackstein 2006
) through its interaction with MadCam-1, preferentially expressed on Peyer's patch high endothelial venules and postcapillary venules in lamina propria (Briskin et al. 1997
VLA-4 is expressed on lymphocytes, monocytes, mast cells, macrophages, basophils and eosinophils, and has key roles in inflammation, cellular adhesion and cellular activation. LPAM-1 is expressed mainly on lymphocytes, and plays a key role in lymphocyte recruitment to sites of inflammation.
