== Function Summary ==
* **Entrez Summary**: N/A
* **UniProt Summary**: 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. {ECO:0000269|PubMed:14722266, ECO:0000269|PubMed:17174307}.
