Summary: Predicted to enable MHC class II protein complex binding activity and peptide antigen binding activity. Predicted to be involved in several processes, including antigen processing and presentation of exogenous peptide antigen via MHC class II; negative regulation of antigen processing and presentation of peptide antigen via MHC class II; and peptide antigen assembly with MHC class II protein complex. Predicted to be located in lysosome. Predicted to be part of MHC class II protein complex. Predicted to be active in late endosome membrane and lysosomal membrane. Is expressed in hemolymphoid system and metanephros. Orthologous to human HLA-DOB (major histocompatibility complex, class II, DO beta). [provided by Alliance of Genome Resources, Nov 2024]

Proper development of long-lived memory CD4 T cells requires HLA-DO function.
Title: Proper development of long-lived memory CD4 T cells requires HLA-DO function.
Mouse MHC class II chaperone H2-O antigen affects the repertoire of presented self-peptides by B cells and thymic epithelium. H2-O induces differential effects on epitope presentation and thymic selection, thereby altering CD4 T-cell precursor frequencies. Lack of H2-O increases autoreactivity and susceptibility to autoimmune disease development.
Title: Lack of the MHC class II chaperone H2-O causes susceptibility to autoimmune diseases.
these results report positional cloning of the gene responsible for production of retrovirus-neutralizing antibodies in mice of the I/LnJ strain; it encodes the beta subunit of the non-classical major histocompatibility complex class II (MHC-II)-like molecule H2-O, a negative regulator of antigen presentation
Title: Neutralizing Antibody Responses to Viral Infections Are Linked to the Non-classical MHC Class II Gene H2-Ob.
H2-O predominantly inhibits antigen presentation in early endosomal compartments. Thus, H2-O appears to skew peptide loading to late endosomal/lysosomal compartments. This may favor presentation of antigens taken up by the B cell receptor.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
