Antigen Details

Structure: C3b is a glycosylated, 176 kD protein that is formed by the cleavage of C3. iC3b is proteolytically derived from C3b and exists as a mixture of 176 and 174 kD proteins.
Distribution: Extracellular fluid, plasma membrane, and serum.
Function: C3b is involved in all three complement pathways and is essential for effective complement activation and presentation of antigens to cells of the adaptive immune system. iC3b is less active than C3b, but the target-bound protein can expand target-specific B-cell and T-cell populations by interacting with lymphoid and phagocytic cells.
Interaction: C3b can bind covalently, via its reactive thioester, to cell surface carbohydrates or immune aggregates. Macrophages and neutrophils have receptors, CR1 (CD35), for C3b. iC3b can also function as opsonin, but it binds through CR2 and CR3.
Ligand/Receptor: C3b can bind to Factor B, Factor P, Factor H, Factor I, C5, DAF (CD55), MCP (CD46), and CR1 (CD35). iC3b can interact with CR2 (CD21), and CR3 (CD11b/CD18).
