MARH9 Rabbit Polyclonal Antibody

MARCH9 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. MARCH9 induces internalization of several membrane glycoproteins and directs them to the endosomal compartment (Bartee et al., 2004 [PubMed 14722266]; Hoer et al., 2007 [PubMed 17174307]) .[supplied by OMIM, Apr 2010], domain:The RING-CH-type zinc finger domain is required for E3 ligase activity., function:E3 ubiquitin-protein ligase that may mediate ubiquitination of MHC-I, CD4 and ICAM1, and promote their subsequent endocytosis and sorting to lysosomes via multivesicular bodies. 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., pathway:Protein modification; protein ubiquitination., similarity:Contains 1 RING-CH-type zinc finger., subunit:Homodimer., tissue specificity:Ubiquitously expressed.
