C1R Summary & Protein Information

C1R Background

Catalytic activity: Selective cleavage of Lys(or Arg)-|-Ile bond in complement subcomponent C1s to form the active form of C1s (EC 3.4.21.42).
Subunit structure: C1 is a calcium-dependent trimolecular complex of C1q, C1r and C1s in the molar ration of 1:2:2. C1r is a dimer of identical chains, each of which is activated by cleavage into two chains, A and B, connected by disulfide bonds.
Post-translational: The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains. {ECO:0000269|PubMed:2820791}.
Sequence similarity: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-ProRule:PRU00274}.; Contains 2 CUB domains. {ECO:0000255|PROSITE-ProRule:PRU00059}.; Contains 1 EGF-like domain. {ECO:0000305}.; Contains 1 peptidase S1 domain. {ECO:0000255|PROSITE-ProRule:PRU00274}.; Contains 2 Sushi (CCP/SCR) domains. {ECO:0000255|PROSITE-ProRule:PRU00302}.
