Summary
[Homo sapiens] C1S associates with C1R and C1Q to form the first component (C1) of the classical complement pathway.
[Homo sapiens] C1S is the modular serine protease responsible for cleavage of C4 and C2, the protein substrates for the first component (C1).
Entrez Gene
Summary This gene does not have any Entrez summary - the following is the summary from its human ortholog ENSG00000182326:
This gene encodes a serine protease, which is a major constituent of the human complement subcomponent C1. C1s associates with two other complement components C1r and C1q in order to yield the first component of the serum complement system. Defects in this gene are the cause of selective C1s deficiency.
