Primary Identifier | MGI:96448 | Organism | mouse, laboratory |
Chromosome | 12 | Mgi Type | gene segment |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables several functions, including antigen binding activity; identical protein binding activity; and immunoglobulin receptor binding activity. Involved in pre-B cell allelic exclusion. Acts upstream of or within several processes, including early endosome to late endosome transport; immunoglobulin mediated immune response; and positive regulation of B cell proliferation. Located in external side of plasma membrane; extracellular space; and perinuclear region of cytoplasm. Part of B cell receptor complex and immunoglobulin complex, circulating. Is active in cytoplasm. Is expressed in several structures, including brain; hemolymphoid system; intestine; and liver. Used to study non-Hodgkin lymphoma and type 1 diabetes mellitus. Human ortholog(s) of this gene implicated in agammaglobulinemia 1. Orthologous to human IGHM (immunoglobulin heavy constant mu). PHENOTYPE: Mice homozygous for a knock-out allele exhibit abnormal immune system morphology and physiology. [provided by MGI curators] |
