Product name:Human CD55 ELISA Kit
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.
CD55 also acts as the receptor for echovirus 7 and related viruses(echoviruses 13, 21, 29 and 33). It is attached to the membrane by a GPI-anchor.
