Gene: H2-Ab1 (histocompatibility 2, class II antigen A, beta 1) Mus musculus
Symbol: H2-Ab1
Name: histocompatibility 2, class II antigen A, beta 1
Description: Exhibits several functions, including peptide antigen binding activity; protein antigen binding activity; and toxic substance binding activity. Involved in several processes, including B cell affinity maturation; antigen processing and presentation of exogenous peptide antigen via MHC class II; and cellular response to interferon-gamma. Localizes to several cellular components, including the MHC class II protein complex; endosome; and external side of plasma membrane. Human ortholog(s) of this gene implicated in several diseases, including autoimmune hypersensitivity disease (multiple); bacterial infectious disease (multiple); bone inflammation disease (multiple); bullous skin disease (multiple); and hematologic cancer (multiple). Is expressed in lung and thymus primordium. Orthologous to human HLA-DQB1 (major histocompatibility complex, class II, DQ beta 1) and HLA-DQB2 (major histocompatibility complex, class II, DQ beta 2); PARTICIPATES IN allograft rejection pathway; antigen processing and presentation pathway; asthma pathway; INTERACTS WITH 17alpha-ethynylestradiol; 2,3,7,8-tetrachlorodibenzodioxine; 2,3,7,8-Tetrachlorodibenzofuran.
Type: protein-coding
RefSeq Status: VALIDATED
