Gene: RT1-B (RT1 class II, locus B) Rattus norvegicus
No known orthologs.
Symbol: RT1-B
Name: RT1 class II, locus B
RGD ID: 3467
Description: Predicted to enable MHC class II protein complex binding activity. Predicted to be involved in 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 integral component of membrane. Predicted to be part of MHC class II protein complex. Human ortholog(s) of this gene implicated in several diseases, including allergic disease (multiple); autoimmune disease (multiple); bacterial infectious disease (multiple); hematologic cancer (multiple); and liver disease (multiple). Orthologous to human HLA-DQB1 (major histocompatibility complex, class II, DQ beta 1).
Type: protein-coding
Previously known as: rano class II histocompatibility antigen, A beta chain; RT1 class II histocompatibility antigen, A beta chain; RT1 region, class II (B); RT1 region, class II, locus B
