Recombinant Human Factor D Protein (His Tag)

Complement factor D; also known as adipsin; is a member of the chymotrypsin family of serine proteases; which plays an essential role in host defense as the rate-limiting enzyme in the alternative pathway of complement activation. Complement factor D activates a convertase (C3bBb) responsible for cleavage of the complement protein C3; which leads to the activation of terminal complement component C5-9 to form the membrane attack complex on microbial or cellular surfaces. It also functions in the regulation of systemic energy balance and physiologic and pathologic processes; including immunity and inflammation.
