Complement factor I.
based on mapping to UniProt P05156
Inactivates complement subcomponents C3b, iC3b and C4b by proteolytic cleavage.
-!- Cleavage of complement subcomponent C3b requires its binding to cofactor H or complement receptor CR1; cleavage of iC3b requires complement receptor CR1; cleavage of C4b requires C4b-binding protein. -!- Belongs to peptidase family S1.
