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 Membrane-bound transcription factor site-2 protease 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 Membrane-bound transcription factor site-2 protease 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 Membrane-bound transcription factor site-2 protease, 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:
Membrane-bound transcription factor site-2 protease, also known as Endopeptidase S2P, plays a pivotal role in intramembrane proteolysis of key regulatory proteins such as ATF6 and SREBP, crucial for lipid metabolism and ER stress response. Its activity is essential for the proteolytic activation of sterol regulatory element-binding proteins, facilitating their nuclear translocation to activate gene transcription.
Therapeutic significance:
The protein's involvement in diseases like IFAP syndrome 1, Olmsted syndrome, Keratosis follicularis spinulosa decalvans, and Osteogenesis imperfecta 19 highlights its clinical relevance. Understanding the role of Membrane-bound transcription factor site-2 protease could open doors to potential therapeutic strategies for these genetic disorders, offering hope for targeted treatments.
