Rabbit anti-Human TTF1 Polyclonal Antibody

Uniprot Id

Q15361

Target Species

Human

Target Name

TTF1

Target Full Name

Transcription termination factor 1

Target 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.

Target Subcellular Location

Nucleus. Nucleus, nucleolus.

Target Research Area

Transcription

Target Synonyms

RNA polymerase I termination factor; Transcription termination factor 1; Transcription termination factor I; Transcription termination factor RNA polymerase I; TTF 1; TTF-1; TTF-I; Ttf1; TTF1_HUMAN

Target Background

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.
