WebNov 26, 2015 · CD55 (decay accelerating factor) is a widely expressed glycosylphosphatidylinositol (GPI) anchor membrane protein that accelerates the decay of cell-surface–bound C3 convertases, thus limiting the formation of the C5 convertase and ultimately formation of the membrane attack complex.
WebMutations affecting GPI that reduce expression of CD59 and decay-accelerating factor on red blood cells result in paroxysmal nocturnal hemoglobinuria. [8] Viruses such as HIV, human cytomegalovirus and vaccinia incorporate host cell CD59 into their own viral envelope to prevent lysis by complement.
