Technical Data
CD49e (Integrin alpha5) (FITC)
CD49e is the integrin alpha5 chain, a 135/25kD heterodimer, that associates noncovalently with CD29, the integrin beta1 subunit, to form the alpha5beta1 very late antigen-5 (VLA-5) complex, a very well established fibronectin receptor that is expressed on many cell types, including thymocytes, T cells, monocytes and platelets. Expression of the VLA-5 heterodimer is increased on activated and memory T cells. It is also found on very early B cells and on activated B lymphocytes. CD49e/CD2-mediated binding to fibronectin provides a costimulatory signal to T cells. It also enhances Fc-gammaR- and complement receptor-mediated phagocytosis, and is involved in monocyte migration into extracellular tissues.1-6
