Target Details

Target: Complement Factor B (CFB)

Alternative Name: Complement Factor B

Background: Complement factor B is a glycosylated protein composed of a single 93,000 Da polypeptide chain. It is an essential component of the alternative pathway of complement activation and is found in plasma at approximately 200 ug/mL. In the presence of Mg++ factor B binds to C3b and the C3b,B complex can be activated by factor D, a serine protease that circulates as an active trypsin-like serine protease.
Description: Human serum/plasma.
Alternative Names: Recombinant CFB

Molecular Weight: 93 kDa

Pathways: Complement System, Proton Transport, Ribonucleoside Biosynthetic Process
