This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Choline/ethanolaminephosphotransferase 1 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 Choline/ethanolaminephosphotransferase 1 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 Choline/ethanolaminephosphotransferase 1, 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:
Choline/ethanolaminephosphotransferase 1, also known as 1-alkenyl-2-acylglycerol choline phosphotransferase, plays a crucial role in phospholipid biosynthesis. It catalyzes the formation of phosphatidylcholine and phosphatidylethanolamine, essential components of cell membranes, from CDP-choline and CDP-ethanolamine, respectively. This enzyme is pivotal in the protein-dependent process of phospholipid transport, ensuring the distribution of phosphatidyl choline to the lumenal surface of cellular membranes.
Therapeutic significance:
Understanding the role of Choline/ethanolaminephosphotransferase 1 could open doors to potential therapeutic strategies. Its involvement in phospholipid biosynthesis and transport underlines its importance in maintaining cellular integrity and function, suggesting that modulation of its activity could have implications in treating diseases related to membrane dysfunction or lipid metabolism disorders.
