Chromosome | 17 | NCBI Gene Number | 14961 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 7.1.0) Enables 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; cellular response to type II interferon; and positive regulation of T-helper 1 type immune response. Acts upstream of or within antigen processing and presentation of exogenous peptide antigen via MHC class II and immune response. Located in Golgi apparatus; endosome; and external side of plasma membrane. Part of MHC class II protein complex. Is expressed in several structures, including adipose tissue; bone; hemolymphoid system; liver; and lung. Used to study dilated cardiomyopathy and myocarditis. 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 several human genes including HLA-DQB1 (major histocompatibility complex, class II, DQ beta 1). PHENOTYPE: Homozygotes for targeted null mutations exhibit depletion of mature CD4+ T cells, deficiency in cell-mediated immune responses, and increased susceptibility to viral infections.
