ID:TTF1_HUMAN DESCRIPTION: RecName: Full=Transcription termination factor 1; Short=TTF-1; AltName: Full=RNA polymerase I termination factor; AltName: Full=Transcription termination factor I; Short=TTF-I; FUNCTION: Multifunctional nucleolar protein that terminates ribosomal gene transcription, mediates replication fork arrest and regulates RNA polymerase I transcription on chromatin. Plays a dual role in rDNA regulation, being involved in both activation and silencing of rDNA transcription. Interaction with BAZ2A/TIP5 recovers DNA-binding activity. SUBUNIT: Oligomer. The oligomeric structure enables to interact simultaneously with two separate DNA fragments. Interacts with BAZ2A/TIP5. SUBCELLULAR LOCATION: Nucleus. Nucleus, nucleolus (By similarity). DOMAIN: The N-terminal region (NRD) inhibits DNA-binding via its interaction with the C-terminal region (By similarity). PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. SIMILARITY: Contains 2 Myb-like domains. SEQUENCE CAUTION: Sequence=AAH62692.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
