Function

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. Also cleaves IGFBP5 and thereby inhibits the trophic effects of IGF1.

Biological Context

Subcellular Location: Secreted; Cell surface
Tissue Specificity: Specifically expressed in male reproductive tissues

Product Specifications
