Entrez Gene Summary for TTF1 Gene

  • This gene encodes a transcription termination factor that is localized to the nucleolus and plays a critical role in ribosomal gene transcription. The encoded protein mediates the termination of RNA polymerase I transcription by binding to Sal box terminator elements downstream of pre-rRNA coding regions. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. This gene shares the symbol/alias 'TFF1' with another gene, NK2 homeobox 1, also known as thyroid transcription factor 1, which plays a role in the regulation of thyroid-specific gene expression.

GeneCards Summary for TTF1 Gene

TTF1 (Transcription Termination Factor, RNA Polymerase I) is a Protein Coding gene. Diseases associated with TTF1 include choreoathetosis, hypothyroidism, and neonatal respiratory distress and neuroendocrine cell hyperplasia of infancy. Among its related pathways are Gene Expression and Insulin secretion. GO annotations related to this gene include chromatin binding. An important paralog of this gene is DMTF1.

UniProtKB/Swiss-Prot for TTF1 Gene

  • 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.
