Signal transducer and activator of transcription 5B - Focused Library Design

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 Signal transducer and activator of transcription 5B 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 Signal transducer and activator of transcription 5B 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 Signal transducer and activator of transcription 5B, 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:

Signal transducer and activator of transcription 5B (STAT5B) plays a pivotal role in cellular responses to cytokines and growth factors. It is essential for mediating the effects of KITLG/SCF and supports hematopoietic/erythroid differentiation by binding to the GAS element and activating transcription.

Therapeutic significance:

STAT5B mutations are linked to Growth hormone insensitivity syndrome with immune dysregulation, both autosomal recessive and dominant forms. These conditions are characterized by growth hormone resistance, short stature, and immune dysregulation, highlighting STAT5B's potential as a therapeutic target.
