This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Barrier-to-autointegration factor 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 Barrier-to-autointegration factor 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 Barrier-to-autointegration factor, 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:
Barrier-to-autointegration factor (BAF) is a pivotal protein involved in various cellular processes, including mitotic nuclear reassembly, chromatin organization, and the DNA damage response. It binds non-specifically to double-stranded DNA, facilitating DNA cross-bridging and playing a crucial role in nuclear membrane formation post-mitosis. BAF's interaction with PARP1 under oxidative stress highlights its role in the DNA damage response, while its involvement in innate immunity against foreign DNA underscores its protective functions within the cell.
Therapeutic significance:
Given its involvement in Nestor-Guillermo progeria syndrome, a condition characterized by severe osteoporosis and lipoatrophy, understanding the role of Barrier-to-autointegration factor could open doors to potential therapeutic strategies. Its multifaceted role in biological systems makes it an intriguing subject for scientific inquiry, particularly in the context of disease mechanisms and therapeutic interventions.
