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 Cdc42-interacting protein 4 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 Cdc42-interacting protein 4 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 Cdc42-interacting protein 4, 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:
Cdc42-interacting protein 4, also known as Protein Felic, Salt tolerant protein, and Thyroid receptor-interacting protein 10, plays a crucial role in cellular processes. It is essential for the translocation of GLUT4 to the plasma membrane in response to insulin signaling, coordinating membrane tubulation with actin cytoskeleton reorganization during endocytosis. This protein binds to specific lipids, promoting membrane invagination and tubule formation, and facilitates CDC42-induced actin polymerization, crucial for endocytic vesicle formation and podosome formation in monocyte-derived cells.
Therapeutic significance:
Understanding the role of Cdc42-interacting protein 4 could open doors to potential therapeutic strategies.
