This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Monoacylglycerol lipase ABHD2 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 Monoacylglycerol lipase ABHD2 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 Monoacylglycerol lipase ABHD2, 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:
Monoacylglycerol lipase ABHD2, also known as 2-arachidonoylglycerol hydrolase, plays a pivotal role in lipid metabolism by catalyzing the hydrolysis of endocannabinoid arachidonoylglycerol (AG) from the cell membrane. This enzyme is activated by progesterone, linking it to reproductive processes. ABHD2's ability to degrade 2AG facilitates sperm capacitation via calcium influx, highlighting its importance in fertility. Additionally, it exhibits ester hydrolase activity, further underscoring its versatile biochemical functions.
Therapeutic significance:
Understanding the role of Monoacylglycerol lipase ABHD2 could open doors to potential therapeutic strategies, particularly in the realm of reproductive health and lipid metabolism disorders. Its unique enzymatic activities offer a promising avenue for targeted interventions.
