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 Regulatory-associated protein of mTOR 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 Regulatory-associated protein of mTOR 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 Regulatory-associated protein of mTOR, 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:
The Regulatory-associated protein of mTOR, also known as p150 target of rapamycin (TOR)-scaffold protein, is a pivotal component of the mTORC1 complex. This complex is a central nutrient sensor that stimulates anabolic reactions, promoting cellular growth by enhancing protein, lipid, and nucleotide synthesis. It achieves this by phosphorylating key substrates such as RPS6KB1 and EIF4EBP1. Concurrently, mTORC1 inhibits autophagy by phosphorylating ULK1, ATG13, and TFEB, thus regulating cellular catabolism.
Therapeutic significance:
Understanding the role of the Regulatory-associated protein of mTOR could open doors to potential therapeutic strategies.
