This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Actin-like protein 6B 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 Actin-like protein 6B 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 Actin-like protein 6B, 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:
Actin-like protein 6B, also known as 53 kDa BRG1-associated factor B, plays a pivotal role in transcriptional activation and repression by altering chromatin structure. It is a crucial component of the SWI/SNF chromatin remodeling complexes, essential for postmitotic neural development and dendritic outgrowth. This protein is involved in the transition from proliferating neural stem cells to neurons, highlighting its importance in neural development.
Therapeutic significance:
Actin-like protein 6B is linked to Developmental and epileptic encephalopathy 76 and Intellectual developmental disorder with severe speech and ambulation defects. Understanding its role could lead to novel therapeutic strategies for these severe neurodevelopmental disorders.
