E3 ubiquitin-protein ligase MARCH11, MARCH-XI, March11, MARHB_HUMAN, Membrane associated ring finger C3HC4 11, Membrane-associated RING finger protein 11, Membrane-associated RING-CH protein XI.
E3 ubiquitin-protein ligase that mediates polyubiquitination of CD4. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfer the ubiquitin to targeted substrates. May play a role
