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 Calcium/calmodulin-dependent protein kinase type II subunit beta 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 Calcium/calmodulin-dependent protein kinase type II subunit beta 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 Calcium/calmodulin-dependent protein kinase type II subunit beta, 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:
Calcium/calmodulin-dependent protein kinase type II subunit beta (CaMK2B) plays a pivotal role in neuronal plasticity, dendritic spine and synapse formation, and the regulation of sarcoplasmic reticulum Ca(2+) transport in skeletal muscle. Its kinase-independent action in bundling actin filaments underscores its structural significance in the reorganization of the actin cytoskeleton during neuronal plasticity, facilitating synaptic plasticity, long-term potentiation, and learning processes in the hippocampus.
Therapeutic significance:
The association of CaMK2B with Intellectual developmental disorder, autosomal dominant 54, highlights its potential as a therapeutic target. Understanding the role of Calcium/calmodulin-dependent protein kinase type II subunit beta could open doors to potential therapeutic strategies, offering hope for interventions in intellectual developmental disorders and enhancing cognitive functions.
