UniProt Comments
General factor that plays a major role in the activation of eukaryotic genes transcribed by RNA polymerase II . Interacts with TBP2 and is required for activated transcription and possibly basal transcription (PubMed:10634912). Plays important roles in pollen tube growth, guidance, and reception as well as endosperm development. Is partially functionally different from TFIIB2 and PBRP2 (PubMed:23547107).
