TBP-class protein binding

Definition

Target type: molecularfunction

Binding to a member of the class of TATA-binding proteins (TBP), including any of the TBP-related factors (TRFs). [GOC:jl, GOC:txnOH, http://www.mblab.gla.ac.uk/, PMID:16858867]

TATA-binding protein (TBP) is a crucial transcription factor that binds to the TATA box, a conserved DNA sequence typically found within gene promoters. Its molecular function involves several steps in the initiation of transcription:

1. **DNA Binding:** TBP recognizes and binds specifically to the TATA box, initiating the assembly of the pre-initiation complex (PIC) at the promoter region. This binding is highly specific and relies on the unique structure of the TATA box and the TBP protein.

2. **DNA Bending:** Upon binding, TBP induces a significant bend in the DNA, facilitating the recruitment of other transcription factors and RNA polymerase II (RNAPII). This bend exposes the DNA to the binding of other PIC components.

3. **Recruitment of Transcription Factors:** TBP acts as a scaffold, recruiting other general transcription factors (GTFs) like TFIIA, TFIIB, TFIIF, TFIIE, and TFIIH. These factors are crucial for the correct positioning and activation of RNAPII at the promoter.

4. **RNAPII Recruitment and Activation:** TBP, along with other GTFs, promotes the recruitment of RNAPII to the promoter. Once assembled, RNAPII can initiate transcription, producing messenger RNA (mRNA) from the gene.

5. **Regulation of Transcription:** TBP plays a critical role in regulating gene expression. Its binding affinity to the TATA box can be modulated by various factors, including:
* **Post-translational modifications:** Phosphorylation, acetylation, and other modifications of TBP can alter its binding affinity.
* **DNA sequence variation:** Subtle variations in the TATA box sequence can influence TBP binding.
* **Interactions with other transcription factors:** TBP can interact with other transcription factors, influencing its binding to the TATA box and the initiation of transcription.

In summary, TBP-class protein binding is essential for the initiation of transcription by acting as a scaffold that recruits and positions other transcription factors and RNAPII at the promoter region. Its function is tightly regulated, ensuring appropriate levels of gene expression.'
