AI-ACCELERATED DRUG DISCOVERY
Available from Reaxense
This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of T-box transcription factor TBX21 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 T-box transcription factor TBX21 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 T-box transcription factor TBX21, 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:
T-box transcription factor TBX21, also known as T-bet, plays a pivotal role in immune response regulation. It orchestrates Th1 lineage development from naive Th precursor cells by activating Th1 genetic programs and repressing Th2 and Th17 programs. TBX21's involvement in activating genes crucial for Th1 cell function, such as IFN-gamma and CXCR3, and its role in chromatin remodeling highlight its significance in immune system functionality.
Therapeutic significance:
TBX21's association with diseases like Asthma, with nasal polyps and aspirin intolerance, and Immunodeficiency 88, underscores its therapeutic potential. Understanding TBX21's role could pave the way for innovative treatments targeting these immune-related conditions.
