Target Information

RNA polymerase III synthesizes tRNA, 5S rRNA, 7SL RNA, and U6 snRNA, and is overexpressed in many transformed cell lines and tumors. Rapidly growing cells require high levels of Pol III–transcribed RNA, which depends on TFIIIB and TFIIIC2 transcription factor complexes.
TFIIIC2 consists of five subunits (TFIIIC220, TFIIIC110, TFIIIC102, TFIIIC90, TFIIIC63) that are overexpressed in malignant cells such as ovarian carcinomas. It recruits RNA Pol III and TFIIIB to promoter elements, playing a role in deregulation of malignancy.
TFIIIB includes the TATA-binding protein (TBP), TFIIB-related factor 1 (TFIIIB90, BRF1), and TFIIIB. Expression of these components is upregulated in transformed cells. In many carcinomas, tumor suppressors RB and p53 are inactivated, affecting their ability to regulate TFIIIB function.
