TF3B

Transcription factor IIIB 90 kDa subunit ;
TFIIIB90 ;
hTFIIIB90 ;
B-related factor 1 ;
BRF-1 ;
hBRF ;
TAF3B2 ;
TATA box-binding protein-associated factor, RNA polymerase III, subunit 2 ;

function:General activator of RNA polymerase which utilizes different TFIIIB complexes at structurally distinct promoters. The isoform 1 is involved in the transcription of tRNA, adenovirus VA1, 7SL and 5S RNA. Isoform 2 is required for transcription of the U6 promoter.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,similarity:Belongs to the TFIIB family.,similarity:Contains 1 TFIIB-type zinc finger.,subunit:TFIIIB comprises at least the TATA-binding protein (TBP) and the B-related factor 1 (BRF1/TFIIIB90). Interacts with BDP1.,
