Multidrug resistance-associated protein 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 Multidrug resistance-associated protein 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 Multidrug resistance-associated protein 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 Multidrug resistance-associated protein 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:

Multidrug resistance-associated protein 1 (MRP1), encoded by the gene with accession number P33527, plays a pivotal role in cellular detoxification. It is known for mediating the export of organic anions and drugs from the cytoplasm, including glutathione and glutathione conjugates, leukotriene C4, estradiol-17-beta-o-glucuronide, methotrexate, antiviral drugs, and other xenobiotics. MRP1 also facilitates the ATP-dependent transport of anticancer drugs, contributing to drug resistance in cancer cells.

Therapeutic significance:

MRP1's involvement in the pathogenesis of Deafness, autosomal dominant, 77, underscores its clinical relevance. This connection highlights the protein's potential as a target for therapeutic intervention in sensorineural hearing loss. Understanding the role of MRP1 could open doors to potential therapeutic strategies, offering hope for treatments that could mitigate or reverse the progression of this form of deafness.
