Solute carrier family 15 member 1 - Focused Library Design

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 Solute carrier family 15 member 1 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 Solute carrier family 15 member 1 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 Solute carrier family 15 member 1, 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:

Solute carrier family 15 member 1 (SLC15A1), also known as Peptide transporter 1, plays a crucial role in nutrient absorption. It is an electrogenic proton-coupled amino-acid transporter, primarily facilitating the uptake of di- and tripeptides from the small intestinal lumen. Its ability to transport neutral and monovalently charged peptides, with a proton to peptide stoichiometry of 1:1 or 2:1, underscores its significance in digestive health. Additionally, SLC15A1 mediates the transepithelial transport of bacterial dipeptides, aiding in the mucosal immune system's recognition of pathogenic bacteria.

Therapeutic significance:

Understanding the role of Solute carrier family 15 member 1 could open doors to potential therapeutic strategies, particularly in enhancing nutrient absorption and bolstering mucosal immunity.
