  • Application notes
    Is unsuitable for ICC/IF.
  • Target

    • Function

      C1s B chain is a serine protease that combines with C1q and C1s to form C1, the first component of the classical pathway of the complement system. C1r activates C1s so that it can, in turn, activate C2 and C4.
    • Involvement in disease

      Defects in C1S are the cause of complement component C1s deficiency (C1SD) [MIM:613783]. A rare defect resulting in C1 deficiency and impaired activation of the complement classical pathway. C1 deficiency generally leads to severe immune complex disease with features of systemic lupus erythematosus and glomerulonephritis.
    • Sequence similarities

      Belongs to the peptidase S1 family.
      Contains 2 CUB domains.
      Contains 1 EGF-like domain.
      Contains 1 peptidase S1 domain.
      Contains 2 Sushi (CCP/SCR) domains.
    • Post-translational
      modifications

      The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.
