Identification
BMDB Protein ID BMDBP01303
Secondary Accession Numbers None
Name Complement C1s subcomponent
Synonyms Not Available
Gene Name C1S
Protein Type Enzyme
Biological Properties
General Function Involved in calcium ion binding
Specific Function 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 (By similarity).
