The complement pathway is an important host defense system that contributes to both innate and acquired immunity.
There are three pathways of complement activation: the classical pathway, lectin pathway and alternative pathway.
Complement protein Factor I is a key serine protease that modulates the complement cascade by regulating the levels of C3 convertases.
It circulates in plasma as a heavily N-glycosylated heterodimer made up of two disulfide linked chains, each carrying three N-linked oligosaccharide chains that may have both structural and functional roles in the interactions with the natural substrate and the cofactor during catalysis.
Factor I is a serine protease with a high degree of specificity for C3b and C4b.
It requires protein cofactors for cleavage of these complement proteins; Factor H, CR1 or MCP are required for C3b cleavage, and C4bp or CR1 are required for C4b cleavage.
