Primary Identifier | MGI:88345 | Organism | mouse, laboratory |
Chromosome | 4 | NCBI Gene Number | 12517 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Predicted to enable carbohydrate binding activity and transmembrane signaling receptor activity. Predicted to be active in plasma membrane. Is expressed in brain; cerebellum external granule cell layer; cerebellum internal granule cell layer; hippocampus; and neocortex. Orthologous to human CD72 (CD72 molecule). PHENOTYPE: Homozygous mutation of this gene results in impaired B cell development and delayed maturation, resulting in reduced numbers of mature B cells and an expansion of pre-B cells. Mice have fewer peripheral mature B-2 cells and more B-1 cells. B cells are hyperproliferative in response to stimuli. [provided by MGI curators] |
