Anti-integrin, alpha 2 antibodies are protein reagents that detect specific antigens. The integrin, alpha 2 antigen is another term for the human protein integrin subunit alpha 2, encoded by the ITGA2 gene. The protein is known to function in organ morphogenesis and cell adhesion, among other biological roles. Canonically, it has an amino acid length of 1181 residues and a mass of 129.3 kilodaltons. Its subcellular localization is in the membrane and it is widely expressed in many tissue types. The integrin, alpha 2 protein is a member of the Integrin alpha chain protein family.
