| Function |
E3 ubiquitin-protein ligase that mediates ubiquitination of TFRC, CD86, FAS and MHC class II proteins, such as HLA-DR alpha and beta, and promotes their subsequent endocytosis and sorting to lysosomes via multivesicular bodies. By constitutively ubiquitinating MHC class II proteins in immature dendritic cells, down-regulates their cell surface localization thus sequestering them in the intracellular endosomal system. {ECO:0000269|PubMed:14722266, ECO:0000269|PubMed:18305173, ECO:0000269|PubMed:18389477, ECO:0000269|PubMed:19117940}.
