H2-Ob - histocompatibility 2, O region beta locus

Predicted to enable MHC class II protein complex 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. 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, Apr 2022]
