RNA polymerase I termination factor Proteins and Enzymes

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 ...
