Complement component 1s
Protein found in humans
Complement component 1s (EC 3.4.21.42, C1 esterase, activated complement C1s, complement C overbar 1r, C1s) is a protein involved in the complement system. C1s is part of the C1 complex. In humans, it is encoded by the C1S gene.
C1s cleaves C4 and C2, which eventually leads to the production of the classical pathway C3-convertase.
