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 Hepatocyte growth factor receptor 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 Hepatocyte growth factor receptor 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 Hepatocyte growth factor receptor, 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 Hepatocyte growth factor receptor, known by its aliases such as HGF/SF receptor, Proto-oncogene c-Met, Scatter factor receptor, and Tyrosine-protein kinase Met, plays a pivotal role in various physiological processes. It transduces signals from the extracellular matrix to the cytoplasm by binding to its ligand, HGF, influencing cell proliferation, survival, and morphogenesis. Its activation triggers multiple signaling cascades crucial for embryonic development, organ regeneration, and tissue remodeling.
Therapeutic significance:
Given its involvement in diseases like Hepatocellular carcinoma, Renal cell carcinoma papillary, and Osteofibrous dysplasia, targeting the Hepatocyte growth factor receptor presents a promising avenue for therapeutic intervention. Its role in these conditions underscores the potential for developing targeted therapies that could inhibit its activity, offering hope for patients suffering from these malignancies.
