Description
Product Characteristics:
MARCH4, an E3 ubiquitin protein ligase, may mediate ubiquitination of MHC I and CD4, and promote their subsequent endocytosis and sorting to lysosomes via multivesicular bodies. E3 ubiquitin protein ligases accept ubiquitin from an E2 ubiquitin conjugating enzyme in the form of a thioester and then directly transfer the ubiquitin to targeted substrates.
Synonyms: E3 ubiquitin protein ligase MARCH4, RNF174, KIAA1399, MARCH 4, MARCH IV, Membrane associated RING CH protein IV, Membrane associated ring finger C3HC4 4, Membrane associated RING finger protein 4, mKIAA1399, RING finger protein 174, MARH4_HUMAN.
Target Information: MARCH4 is a member of the MARCH family of membrane-bound E3 ubiquitin ligases (EC 6.3.2.19). MARCH enzymes add ubiquitin (see MIM 191339) to target lysines in substrate proteins, thereby signaling their vesicular transport between membrane compartments. MARCH4 reduces surface accumulation of several membrane glycoproteins by directing them to the endosomal compartment (Bartee et al., 2004 [PubMed 14722266]).[supplied by OMIM, Apr 2010]
