Complement iC3b, Human Complement iC3b, Human iC3b
Native, human iC3b complement component. iC3b is formed by the cleavage of C3b by Factor I in the presence of Factor H, CR1, or membrane cofactor protein. Factor I cleavage of C3b to iC3b inactivates and prevents C3b from functioning in the C3 or C5 convertase enzymes. The iC3b fragment thus produced is a glycoprotein composed of two C3α′ polypeptides of M.W. 43 kDa and M.W. 63 kDa which are disulfide bonded to the intact C3 β-chain (M.W. 75 kDa). iC3b interaction with CR3 (CD11b/CD18) receptors present on a variety of white blood cells greatly enhances phagocytosis of iC3b coated target cells or particles.
