This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Cytochrome P450 4X1 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 Cytochrome P450 4X1 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 Cytochrome P450 4X1, 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:
Cytochrome P450 4X1, alternatively known as CYPIVX1, plays a crucial role in the metabolism of endocannabinoids, particularly through the epoxidation of anandamide's arachidonoyl moiety. This enzyme, a cytochrome P450 monooxygenase, is unique in its selective catalytic activity, which does not extend to fatty acids, steroids, or prostaglandins. It operates by inserting one oxygen atom into its substrate and reducing the second oxygen atom into water, utilizing electrons supplied by NADPH via cytochrome P450 reductase.
Therapeutic significance:
Understanding the role of Cytochrome P450 4X1 could open doors to potential therapeutic strategies, especially in modulating endocannabinoid signaling, which is pivotal in various physiological processes.
