UniProtKB description: Plays a role in the inhibition of both the innate and adaptive immune responses. Possesses two N-terminal domains that bind the Fc region of IgG and two domains that form a tripartite complex with complement factors C3b and CFH. By recruiting CFH and C3b, the secreted form acts as a potent complement inhibitor of the alternative pathway-mediated lysis.
