2.7.7.6 | transcription factor TFIIIB |
proper initiation by RNA pol III requires the transcription factor TFIIIB. Gene-external U6 snRNA transcription requires TFIIIB consisting of Bdp1, TBP, and Brf2. Transcription from the gene internal tRNA promoter requires TFIIIB composed of Bdp1, TBP, and Brf1. Breast cancer susceptibility gene 1, BRCA1, inhibits TFIIB, which interacts with the BRCA1 C-terminal region domain of Fcp1p, an RNA polymerase II phosphatase, TFIIIB regulation network, overview |
