TTF1 also known as Transcription Termination Factor 1 plays a critical role in transcription termination of ribosomal RNA genes. This protein with a molecular mass of approximately 90 kDa specifically binds to terminator sequences facilitating the release of paused RNA polymerase I. TTF1 is widely expressed in eukaryotic cells particularly in tissues with high rates of ribosomal RNA synthesis like the nucleolus within the nucleus. Its presence is essential for the proper termination and recycling of the transcription machinery enhancing the efficiency of ribosomal RNA production.

Biological function summary

TTF1 influences the regulation and expression of ribosomal RNA by forming a complex with other factors to ensure successful transcription termination and reinitiation. It interacts with co-factors such as Nucleolin and facilitates the looping of DNA which is a necessary component of efficient termination. This function supports cellular growth and proliferation by maintaining high levels of ribosome synthesis which is essential for protein translation.

Pathways

TTF1 is significantly associated with the nucleolar transcription termination pathway and is integral to the modulation of ribosomal RNA synthesis. It works alongside proteins such as RNA Polymerase I and Transcription Initiation Factor SL1 forming a relationship that ensures efficient transcriptional processes. TTF1 helps maintain the balance between transcription initiation elongation and termination important for the homeostasis of cell proliferation and growth pathways.

TTF1 dysregulation relates to oncogenesis and certain ribosomopathies where abnormal ribosome function can occur. Overexpression or mutation of TTF1 can lead to increased ribosome production contributing to the unrestrained growth seen in certain cancers. It collaborates with proteins such as c-Myc which is known for promoting cell proliferation and is frequently upregulated in cancerous cells. Understanding TTF1's role offers insights into potential therapeutic targets for treating these conditions.

靶点信息

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.
