MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a transcriptional activator that binds to the PU-box (5'-GAGGAA-3') and acts as a lymphoid-specific enhancer. Four transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]
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]
