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 F-box/WD repeat-containing protein 1A 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 F-box/WD repeat-containing protein 1A 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 F-box/WD repeat-containing protein 1A, 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:
F-box/WD repeat-containing protein 1A, also known as E3RSIkappaB, plays a pivotal role in cellular processes by being a part of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex. This complex is crucial for the ubiquitination and subsequent proteasomal degradation of target proteins, including those involved in Wnt signaling, NF-kappa-B activation, and cell cycle regulation. Its ability to recognize and bind to phosphorylated target proteins underscores its significance in cellular signaling pathways.
Therapeutic significance:
Understanding the role of F-box/WD repeat-containing protein 1A could open doors to potential therapeutic strategies. Its involvement in key signaling pathways like Wnt and NF-kappa-B suggests its potential as a target in diseases where these pathways are dysregulated.
