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 DNA-binding protein SATB2 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 DNA-binding protein SATB2 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 DNA-binding protein SATB2, 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:
DNA-binding protein SATB2, also known as Special AT-rich sequence-binding protein 2, plays a pivotal role in DNA recognition and transcription regulation. It binds to DNA at nuclear matrix- or scaffold-associated regions, recognizing the sugar-phosphate structure of double-stranded DNA. SATB2 is crucial for chromatin-loop remodeling, acting as a docking site for chromatin remodeling enzymes and influencing gene expression by recruiting corepressors or coactivators directly to promoters and enhancers.
Therapeutic significance:
SATB2's involvement in cleft palate isolated, a congenital fissure of the soft and/or hard palate, underscores its therapeutic significance. Understanding the role of SATB2 could open doors to potential therapeutic strategies for not only cleft palate but also other craniofacial dysmorphic features, intellectual disability, and osteoporosis linked to its dysfunction.
