This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Transcription initiation factor TFIID subunit 6 including:
1. LLM-powered literature research
Our custom-tailored LLM extracted and formalized all relevant information about the protein from a large set of structured and unstructured data sources and stored it in the form of a Knowledge Graph. This comprehensive analysis allowed us to gain insight into Transcription initiation factor TFIID subunit 6 therapeutic significance, existing small molecule ligands, relevant off-targets, and protein-protein interactions.

2. AI-Driven Conformational Ensemble Generation
Starting from the initial protein structure, we employed advanced AI algorithms to predict alternative functional states of Transcription initiation factor TFIID subunit 6, including large-scale conformational changes along "soft" collective coordinates. Through molecular simulations with AI-enhanced sampling and trajectory clustering, we explored the broad conformational space of the protein and identified its representative structures. Utilizing diffusion-based AI models and active learning AutoML, we generated a statistically robust ensemble of equilibrium protein conformations that capture the receptor's full dynamic behavior, providing a robust foundation for accurate structure-based drug design.

3. Binding pockets identification and characterization
We employed the AI-based pocket prediction module to discover orthosteric, allosteric, hidden, and cryptic binding pockets on the protein’s surface. Our technique integrates the LLM-driven literature search and structure-aware ensemble-based pocket detection algorithm that utilizes previously established protein dynamics. Tentative pockets are then subject to AI scoring and ranking with simultaneous detection of false positives. In the final step, the AI model assesses the druggability of each pocket enabling a comprehensive selection of the most promising pockets for further targeting.

Background:
Transcription initiation factor TFIID subunit 6, also known as TAF6, plays a pivotal role in the initiation of RNA polymerase II-dependent transcription. It is a part of the TFIID basal transcription factor complex, crucial for recognizing and binding promoters, facilitating the assembly of the pre-initiation complex. TAF6's ability to form homodimers connects various modules of the TFIID complex, establishing a structural core essential for transcriptional regulation.
Therapeutic significance:
TAF6's involvement in transcriptional regulation and apoptosis, particularly through its role in up-regulating genes like GADD45A and CDKN1A/p21, highlights its potential in influencing cell fate decisions. Its association with Alazami-Yuan syndrome underscores the therapeutic significance of understanding TAF6's function. Exploring TAF6's mechanisms could unveil novel therapeutic strategies for managing diseases linked to transcriptional dysregulation.
