C1S is activated following association of the C1 complex with immunoglobulins (IgG or IgM) complexed with antigens to form antigen-antibody complexes on the surface of pathogens (PubMed:34155115). C1S is cleaved and activated by C1R to generate C1s subcomponent heavy and light chains (PubMed:11445589, PubMed:6271784). C1s subcomponent light chain then cleaves and activates C2 and C4, the next components of the classical complement pathway (PubMed:16169853, PubMed:467643, PubMed:6282646, PubMed:6319179, PubMed:6906228, PubMed:70787, PubMed:9422791). {ECO:0000269|PubMed:11445589, ECO:0000269|PubMed:16169853, ECO:0000269|PubMed:34155115, ECO:0000269|PubMed:417728, ECO:0000269|PubMed:467643, ECO:0000269|PubMed:6271784, ECO:0000269|PubMed:6282646, ECO:0000269|PubMed:6319179, ECO:0000269|PubMed:6906228, ECO:0000269|PubMed:70787, ECO:0000269|PubMed:9422791}., [Complement C1s subcomponent light chain]: Serine protease component of the complement C1 complex, which catalyzes cleavage and activation of C2 and C4, the next components of the classical complement pathway (PubMed:16169853, PubMed:22949645, PubMed:417728, PubMed:467643, PubMed:6282646, PubMed:6319179, PubMed:70787, PubMed:9422791). Also able to cleave C1 inhibitor (SERPING1) in vitro, additional evidence is however required to confirm this result in vivo (PubMed:16169853). Also cleaves IGFBP5 and thereby inhibits the trophic effects of IGF1 (PubMed:18930415). {ECO:0000269|PubMed:16169853, ECO:0000269|PubMed:18930415, ECO:0000269|PubMed:22949645, ECO:0000269|PubMed:417728, ECO:0000269|PubMed:467643, ECO:0000269|PubMed:6282646, ECO:0000269|PubMed:6319179, ECO:0000269|PubMed:70787, ECO:0000269|PubMed:9422791}.,C1S,C1s proenzyme is a 79.8 kDa glycoprotein produced primarily by hepatocytes but also by other cells. The proenzyme is produced as a single-chain polypeptide of 688 aa. Upon activation the peptide is cleaved between R437 and I438 giving the activated enzyme consisting of two disulfide-linked chains, A chain (52.2 kDa) and B chain (27.7 kDa). The Ca-dependent catalytic subunit of the C1 complex (C1q, C1r, C1s) comprises of two C1s and two C1r molecules and this serine protease tetramer is responsible for the initial steps in the classical complement pathway, cleavage of C4 and C2.

Poids moléculaire: Pro-enzyme C1s (pro-C1s) appears as a single-chain polypeptide around 80 kDa. Upon activation, it is cleaved into two disulfide-linked chains: a ~57 kDa A-chain and and 27 kDa B-chain).
