165 kDa (Wright, 1988)

CD11b is the 165 kDa α-chain of the Mac-1 complex. The molecule, also called CR3, functions as a cell surface receptor for the C3bi complement fragment. There is evidence that CD11b can bind fibrinogen in addition to C3bi (Wright,1988). Two binding sites have now been reported, one recognizing lipopolysaccharide, and the other protein ligands containing the arg-gly-asp sequence (Wright, 1989). Binding of the coagulation factor X has also been suggested as an additional receptor role of CD11b (Altieri,1988). This protein belings to a family of related heterodimeric proteins designated CD11 in the classification system for human leucocyte differentiation antigens, which shares a common β-chain with a MW of 95 kDa (CD18). Besides the C3bi receptor, this protein family contains two other members, leucocyte function associated-1 (LFA-1, C11a) antigen and p150,95 protein (CD11c) (Sanchez-Madrid,1983).
