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 Antiviral innate immune response receptor RIG-I 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 Antiviral innate immune response receptor RIG-I 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 Antiviral innate immune response receptor RIG-I, 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 Antiviral innate immune response receptor RIG-I, also known as ATP-dependent RNA helicase DDX58, plays a pivotal role in the innate immune system. It detects viral RNAs in the cytoplasm, triggering a signaling cascade that results in the production of type I interferons and pro-inflammatory cytokines. This receptor's ability to sense both positive and negative strand RNA viruses, including influenza, hepatitis C, and SARS-CoV-2, underscores its critical function in antiviral defense.
Therapeutic significance:
RIG-I's involvement in Singleton-Merten syndrome 2, characterized by aortic calcification and skeletal abnormalities, highlights its potential as a therapeutic target. Understanding the role of RIG-I could open doors to potential therapeutic strategies for treating viral infections and associated immune disorders.
