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 NF-kappa-B inhibitor alpha 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 NF-kappa-B inhibitor alpha 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 NF-kappa-B inhibitor alpha, 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:
NF-kappa-B inhibitor alpha, also known as I-kappa-B-alpha and Major histocompatibility complex enhancer-binding protein MAD3, plays a crucial role in inhibiting the activity of NF-kappa-B/REL complexes. This protein traps REL dimers in the cytoplasm, preventing their nuclear translocation. Upon cellular stimulation, it becomes phosphorylated, leading to its degradation and allowing RELA dimers to activate transcription in the nucleus.
Therapeutic significance:
Ectodermal dysplasia and immunodeficiency 2 (EDAID2), a disease marked by abnormal ectodermal development and increased infection susceptibility, is associated with mutations in NF-kappa-B inhibitor alpha. Understanding the role of NF-kappa-B inhibitor alpha could open doors to potential therapeutic strategies for EDAID2 and related immunodeficiencies.
