Background: Complement Factor I

Factor I is a plasma protein of molecular weight 88 kDa, consisting of two disulphide linked chains of 50 and 38 kDa. Factor I is a serine protease with a high degree of specificity for C3b and C4b. It has a requirement for protein cofactors for cleavage of these complement proteins, Factor H, CR1 or MCP are required for C3b cleavage and C4bp or CR1 for C4b cleavage.

Alternate Names

C3b Inactivator, CFI

Gene Symbol
