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}. |RINGv| |MHC protein binding| |trans-Golgi network membrane| |antigen processing and presentation of peptide antigen via MHC class II| |antigen processing and presentation of peptide or polysaccharide antigen via MHC class II| |late endosome membrane| |cytoplasmic vesicle membrane| |early endosome membrane| |antigen processing and presentation of peptide antigen| |antigen processing and presentation| |ubiquitin protein ligase activity| |ubiquitin-protein transferase activity| |lysosome| |endosome| |protein polyubiquitination| |lysosomal membrane| |protein ubiquitination| |protein modification by small protein conjugation| |zinc ion binding| |endoplasmic reticulum membrane| |protein modification by small protein conjugation or removal| |immune response| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp129|Isonicotinamide 500μM R03 exp129]]|-2.12| |[[:results:exp6|Bortezomib 0.005μM R00 exp6]]|-1.72| |[[:results:exp82|Torin1 0.08μM R02 exp82]]|1.72| |[[:results:exp71|KU-0063794 3.8μM R02 exp71]]|2.18| |[[:results:exp69|Deguelin 0.05μM R02 exp69]]|2.21| No correlation found to any other genes in chemogenomics.
