Transcription factor IIIB 50 kDa subunit

Transcription factor IIIB 50 kDa subunit (TFIIIB50) also known as b-related factor 2 (BRF-2) is a is_associated_with::protein that in humans is encoded by the BRF2 is_associated_with::gene.

Function
This gene encodes one of the multiple subunits of the is_associated_with::RNA polymerase III transcription factor complex required for transcription of genes with promoter elements upstream of the initiation site. The product of this gene, a TFIIB-like factor, is directly recruited to the is_associated_with::TATA box of polymerase III small nuclear RNA gene promoters through its interaction with the is_associated_with::TATA-binding protein.
