background

Decay Accelerating Factor (or CD55) is a major regulator of the alternative and classical pathways of complement activation and is expressed on all serum-exposed cells. It is commonly hijacked by invading pathogens, including many enteroviruses and uropathogenic Escherichia coli, to promote cellular attachment prior to infection.

molecular weight

The protein has a predicted MW of 35.8 kDa. Due to glycosylation, the protein migrates to 70-75 kDa based on Tris-Bis PAGE result.

available size

100 µg, 500 µg

endotoxin

Less than 1EU per μg by the LAL method.

Function
This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade (PubMed:7525274). Inhibits complement activation by destabilizing and preventing the formation of C3 and C5 convertases, which prevents complement damage (PubMed:28657829).; (Microbial infection) Acts as a receptor for Coxsackievirus A21, coxsackieviruses B1, B3 and B5.; (Microbial infection) Acts as a receptor for Human enterovirus 70 and D68 (Probable).; (Microbial infection) Acts as a receptor for Human echoviruses 6, 7, 11, 12, 20 and 21.
