Ett inaktiverat fragment av komplement 3b (C3b). Faktor H gör C3b tillgängligt för faktor I (tidigare kallat KAF, C3bINF eller enzym 3b-inaktivator), så att iC3b bildas. Därefter klyver faktor I och ett trypsinliknande proteolytiskt enzym iC3b i C3c och C3dg. Serumproteaser bryter sedan ner C3dg i komplement 3d (C3d) och C3g.
A 302-amino-acid fragment in the alpha chain (672-1663) of C3b. It is generated when C3b is inactivated (iC3b) and its alpha chain is cleaved by COMPLEMENT FACTOR I into C3c, and C3dg (955-1303) in the presence COMPLEMENT FACTOR H. Serum proteases further degrade C3dg into C3d (1002-1303) and C3g (955-1001).
