Summaries for C1S Gene

Entrez Gene Summary for C1S Gene

  • 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. [provided by RefSeq, Mar 2009]

GeneCards Summary for C1S Gene

C1S (Complement Component 1, S Subcomponent) is a Protein Coding gene. Diseases associated with C1S include c1s deficiency and capillary leak syndrome. Among its related pathways are Complement and coagulation cascades and Complement and coagulation cascades. GO annotations related to this gene include calcium ion binding and serine-type endopeptidase activity. An important paralog of this gene is HP.

UniProtKB/Swiss-Prot for C1S Gene

  • C1s B chain is a serine protease that combines with C1q and C1r 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
