Chromosome | 7 | NCBI Gene Number | 272382 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables DNA-binding transcription factor activity. Involved in immature B cell differentiation. Acts upstream of or within macrophage differentiation and regulation of DNA-templated transcription. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. Is expressed in brain and liver. Orthologous to human SPIB (Spi-B transcription factor). PHENOTYPE: Homozygous null mice exhibit severe defects in B cell function and selective T cell-dependent humoral immune responses. Mutant B cells display a defective germinal center reaction upon immunization with DNP-KLH and proliferate poorly in vitro in responseto IgM cross-linking. [provided by MGI curators] |
