TAF3B2 Definition

Encoded by human BRF1 Gene (TFIIB Family), alternative isoforms 1 (677-aa, 74-kD), 2 (134-aa, altered N- and C-termini), 3 (473-aa, shorter N-terminus), and 4 (242-aa) of General Transcription Factor 3B 90-kD Subunit function at different promoters on tRNA, 5S rRNA, and other small RNA genes. Related to GTF2B (N-terminus), GTF3B contains a highly charged region and HMG2-related region. Essential for transcription initiation, GTF3B (C-terminus) binds TBP (collectively, TFIIIB) as one of three RNA polymerase III transcription factor subunits. Following GTF3A or GTF3C recognition of promoter elements, GTF3B and RNA polymerase III bind sequentially. (NCI)
