Background: RNA polymerase I termination factor

The TTF1 gene encodes a 905 amino acid long, 103 kDA transcription termination factor 1 protein, also known as a RNA polymerase I termination factor, which functions in terminating ribosomal gene transcription. Additionally, it regulates fork arrest replication and RNA polymerase I transcription on chromatin. Through monitoring the activation as well as the silencing of rDNA transcription, TTF1 acts in rDNA regulation. TTF1 functions in RNA polymerase I transcription as well as mitochondrial transcription and gene expression. It is known to interact with genes PTRF, NFATC3, BAZ2A, SMAD1, and SMAD7. TTF1 has been researched regarding its role in lung cancer, small cell carcinoma, sex cord-gonadal stromal tumor, thyroiditis, blastoma, adenocarcinoma, desmoplastic small round cell tumors, and hirschsprung's disease.
