Summary: Predicted to enable several functions, including MHC class II receptor activity; peptide antigen binding activity; and signaling receptor binding activity. Predicted to be involved in several processes, including antigen processing and presentation of exogenous peptide antigen via MHC class II; peptide antigen assembly with MHC class II protein complex; and positive regulation of T cell activation. Predicted to be located in external side of plasma membrane and immunological synapse. Predicted to be part of MHC class II protein complex. Predicted to be active in late endosome membrane and lysosomal membrane. Human ortholog(s) of this gene implicated in several diseases, including asthma (multiple); autoimmune disease (multiple); bacterial infectious disease (multiple); eye disease (multiple); and sarcoidosis (multiple). Orthologous to several human genes including HLA-DRB1 (major histocompatibility complex, class II, DR beta 1); HLA-DRB3 (major histocompatibility complex, class II, DR beta 3); and HLA-DRB4 (major histocompatibility complex, class II, DR beta 4).

What's a GeneRIF?

our findings suggest that the H2-E2 or RT1-D2 molecules could function as Ag-presenting molecules for a particular class of Ags, as modulators of Ag presentation like nonclassical nonpolymorphic class II molecules

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.
