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 ERO1-like protein beta 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 ERO1-like protein beta 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 ERO1-like protein beta, 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:
ERO1-like protein beta, also known as Endoplasmic reticulum oxidoreductase beta, plays a crucial role in disulfide bond formation within the endoplasmic reticulum. It primarily reoxidizes P4HB/PDI, facilitating continuous rounds of disulfide bond formation. This protein also interacts with other members of the protein disulfide isomerase family, albeit at varying efficiencies, and contributes to the production of reactive oxygen species through electron transfer to molecular oxygen.
Therapeutic significance:
Understanding the role of ERO1-like protein beta could open doors to potential therapeutic strategies, particularly in diseases where disulfide bond formation is disrupted or in conditions characterized by oxidative stress.
