Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Acts upstream of or within B cell homeostasis; hematopoietic progenitor cell differentiation; and negative regulation of B cell proliferation. Located in external side of plasma membrane. Is expressed in hippocampus and renal vasculature. Used to study systemic lupus erythematosus. Human ortholog(s) of this gene implicated in common variable immunodeficiency 2. Orthologous to human TNFRSF13B (TNF receptor superfamily member 13B). PHENOTYPE: Nullizygous mice show increased B cell numbers and splenomegaly. Homozygotes for a null allele show impaired T cell-independent immune responses and isotype switching. Homozygotes for another null allele develop lymphoproliferation and fatal autoimmune nephritis with high titers of autoantibodies. [provided by MGI curators] |
