This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Influenza virus NS1A-binding protein 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 Influenza virus NS1A-binding protein 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 Influenza virus NS1A-binding protein, 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 Influenza virus NS1A-binding protein. 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 Influenza virus NS1A-binding protein. This approach allows us to achieve an excellent hit rate and to identify compounds ready for advanced lead discovery and optimization.

Background:
The Influenza virus NS1A-binding protein, also known as Aryl hydrocarbon receptor-associated protein 3 or Kelch-like protein 39, plays a pivotal role in cellular functions such as pre-mRNA splicing, the AHR pathway, F-actin organization, and protein ubiquitination. It stabilizes actin filaments, protects against cell death, modifies the AHR pathway, and regulates ubiquitin-mediated proteolysis of tumor suppressors.
Therapeutic significance:
Linked to Immunodeficiency 70, characterized by HPV-associated warts, recurrent infections, and autoinflammatory features, this protein's understanding could lead to novel therapeutic strategies for managing this immunodeficiency and potentially other related autoimmune disorders.
