### TAF11 Gene Overview

**Gene Symbol:** TAF11  
**Role:** TAF11 is a crucial component of the TFIID transcription factor complex, playing an essential role in the initiation of RNA polymerase II-dependent transcription. It serves as a small subunit that interacts with the TATA-binding protein (TBP) and is involved in the assembly of the pre-initiation complex (PIC). TAF11, in conjunction with TAF13 and TBP, facilitates promoter binding by TFIID and TFIIA during transcription initiation.

### 1. Associated Genes
While the provided information mentions TAF11’s interaction with TBP and TAF13, it is part of a larger family of TBP-associated factors (TAFs), which also include:
- TAF1
- TAF2
- TAF3
- TAF4
- TAF5
- TAF6
- TAF7
- TAF8
- TAF9
- TAF10
- TAF12

These associated genes work cooperatively within the TFIID complex to recognize and bind to DNA promoters, modulating transcriptional regulation.

### 2. Age-Related Associations
Current research indicates links between transcriptional regulation and aging; however, specific associations between TAF11 and age-related diseases are not well-documented. Changes in transcription factor activity and TAF expression have been implicated in cellular senescence and age-related decline, but further studies are necessary to directly connect TAF11 to specific aging phenotypes or age-related diseases such as cancer, neurodegeneration, or cardiovascular diseases.

### 3. Drug Interactions
To date, there are no specific drugs or classes of drugs that have been definitively documented to interact with TAF11 directly in clinical settings. However, compounds targeting general transcription mechanisms or broad-spectrum inhibitors of RNA polymerases may indirectly influence the function of TFIID complexes. Further research into small molecules or therapeutic strategies that target transcription factors like TAF11 is warranted.

### 4. Pathways and Biological Processes
TAF11 is involved in several key biological processes, including:
- **Transcription Initiation from RNA Polymerase II Promoter:** TAF11 is essential for the assembly of the TFIID complex at promoters, facilitating the proper positioning of RNA polymerase II for transcription initiation.
- **Regulation of Gene Expression:** As part of the TFIID complex, TAF11 participates in the regulation of gene expression in response to various cellular signals.
- **Formation of the Pre-Initiation Complex (PIC):** TAF11 plays a role in the stable assembly of the PIC, which is critical to the transcriptional activation of genes.
- **Coactivation of Transcription Factors:** TAF11 may function as a coactivator, potentially enhancing transcriptional activity through its interactions with various transcription factors.

### Summary
TAF11 is a key subunit of the TFIID transcription factor complex, vital for RNA polymerase II transcription initiation. It interacts with numerous associated factors, plays significant roles across various biological pathways, and could have implications in aging, though specific associations remain to be fully explored. Currently, there are no known direct drug interactions, indicating the need for further research in therapeutic contexts.
