This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Proteasome subunit beta type-8 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 Proteasome subunit beta type-8 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 Proteasome subunit beta type-8, 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:
Proteasome subunit beta type-8, also known as PSMB8, plays a pivotal role in the proteasome complex, a key enzyme in protein degradation. It is involved in antigen processing, generation of spliced peptides, and plays a crucial role in the immune response and apoptosis. PSMB8 is essential for the differentiation of preadipocytes into adipocytes and has a significant role in the inflammatory response pathway.
Therapeutic significance:
The mutation in PSMB8 is linked to Proteasome-associated autoinflammatory syndrome 1, a disorder marked by recurrent fever, joint stiffness, and severe skin lesions. Understanding the role of PSMB8 could open doors to potential therapeutic strategies for treating this autoinflammatory disorder and possibly other conditions related to immune dysregulation.
