Target

Full Name

BRF1, RNA Polymerase III Transcription Initiation Factor Subunit

Introduction

BRF1 is one of the three subunits of the RNA polymerase III transcription factor complex. This complex plays a central role in transcription initiation by RNA polymerase III on genes encoding tRNA, 5S rRNA, and other small structural RNAs. BRF1 belongs to the TF2B family.

2972

UniProt ID

Q92994

Alternative Names

BRF1, RNA Polymerase III Transcription Initiation Factor Subunit; TATA Box Binding Protein (TBP)-Associated Factor, RNA Polymerase III, GTF3B Subunit 2; BRF1, RNA Polymerase III Transcription Initiation Factor 90 KDa Subunit; TFIIIB90; TAF3B2; GTF3B; TAF3C; BRF-1; HBRF; BRF; BRF1 Homolog, Subunit Of RNA Polymerase III Transcription Initiation Factor IIIB (S. Cerevisiae); BRF1 Homolog, Subunit Of RNA Polymerase III Transcription Initiation Factor IIIB; 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.
