RNA-binding protein Nova-2 - 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 RNA-binding protein Nova-2 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 RNA-binding protein Nova-2 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 RNA-binding protein Nova-2, 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.

4. AI-Powered Virtual Screening

Our ecosystem is equipped to perform AI-driven virtual screening on RNA-binding protein Nova-2. With access to a vast chemical space and cutting-edge AI docking algorithms, we can rapidly and reliably predict the most promising, novel, diverse, potent, and safe small molecule ligands of RNA-binding protein Nova-2. This approach allows us to achieve an excellent hit rate and to identify compounds ready for advanced lead discovery and optimization.

Background:

RNA-binding protein Nova-2, also known as Neuro-oncological ventral antigen 2, plays a pivotal role in the regulation of alternative splicing in neurons. It specifically binds to the sequences 5'-YCAY-3', influencing exon inclusion or exclusion. This protein's unique ability to regulate splicing events of axon guidance related genes is crucial for the development of the central nervous system, affecting neural networks wiring and synapse formation.

Therapeutic significance:

Nova-2 is linked to a neurodevelopmental disorder with or without autistic features and/or structural brain abnormalities, characterized by intellectual disability and motor coordination issues. Understanding the role of RNA-binding protein Nova-2 could open doors to potential therapeutic strategies for these conditions.
