This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of GATOR1 complex protein NPRL3 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 GATOR1 complex protein NPRL3 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 GATOR1 complex protein NPRL3, 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 GATOR1 complex protein NPRL3 plays a pivotal role in cellular metabolism by regulating the mTORC1 pathway, a key signaling pathway that responds to amino acid availability. This regulation is crucial for maintaining cellular homeostasis and responding to nutritional changes. NPRL3, through its involvement in the GATOR1 complex, inhibits mTORC1 signaling in the absence of amino acids, showcasing its integral role in cellular nutrient sensing mechanisms.
Therapeutic significance:
Given its central role in the mTORC1 pathway, NPRL3 is linked to familial focal epilepsy with variable foci 3, a condition characterized by focal seizures and potential intellectual disability or autism spectrum disorders. Understanding the role of NPRL3 could open doors to potential therapeutic strategies for treating epilepsy and related neurological conditions.
