C1r along with C1q and C1s form the C1 complex, which is the first component of the serum complement system. C1r is an enzyme that activates C1s to its active form, by proteolytic cleavage.

Clinical significance

Function

C1r has been shown to interact with C1s. C1r cleaves C1s to form the active form of C1s.[9][10]
