FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] TATA binding protein (TBP) and TBP-associated factors (TAFs) participate in the formation of the TFIID protein complex, which is involved in initiation of transcription of genes by RNA polymerase II. This gene encodes a cell type-specific TAF that may be responsible for mediating transcription by a subset of activators in B cells. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jun 2014]
PHENOTYPE: Homozygotes for a targeted null mutation are infertile due to a granulosa cell defect preventing normal follicle formation. [provided by MGI curators]
