Protein Name: C4b-binding protein

UniprotKB/SwissProt ID: P08607 (P08607)

Gene Name: C4bpa

Organism: Mus musculus (Mouse)

Function: Controls the classical pathway of complement activation. It binds as a cofactor to C3b/C4b inactivator (C3bINA), which then hydrolyzes the complement fragment C4b. It also accelerates the degradation of the C4bC2a complex (C3 convertase) by dissociating the complement fragment C2a. Alpha chain binds C4b. It also interacts with serum amyloid P component

Protein Subcellular Localization: Secreted
