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 Guanylate-binding protein 5 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 Guanylate-binding protein 5 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 Guanylate-binding protein 5, 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:
Guanylate-binding protein 5 (GBP5) is a pivotal player in the innate immune response, characterized by its unique ability to hydrolyze GTP without producing GMP. Unlike other family members, GBP5 is specifically recruited to pathogen-containing vacuoles or vacuole-escaped bacteria, enhancing the assembly of inflammasomes. It facilitates the lysis of these vacuoles, releasing pathogens into the cytosol and thereby promoting the recruitment of bacterial cytolysis mediators. This process liberates ligands detected by inflammasomes, crucial for activating the non-canonical CASP4/CASP11 and AIM2 inflammasomes, and selectively assembles the NLRP3 inflammasome in response to microbial agents.
Therapeutic significance:
Understanding the role of Guanylate-binding protein 5 could open doors to potential therapeutic strategies, particularly in enhancing innate immune responses and inflammasome assembly for combating bacterial, viral, and protozoan pathogens.
