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 Glutamate receptor ionotropic, kainate 2 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 Glutamate receptor ionotropic, kainate 2 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 Glutamate receptor ionotropic, kainate 2, 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:
Glutamate receptor ionotropic, kainate 2, also known as Excitatory amino acid receptor 4 or Glutamate receptor 6, plays a pivotal role in the central nervous system as an ionotropic glutamate receptor. It transforms chemical signals into electrical impulses through the binding of L-glutamate, facilitating rapid communication between neurons. Additionally, it exhibits thermoreceptor activity, sensitive to cold temperatures, particularly in dorsal root ganglion neurons.
Therapeutic significance:
This protein is implicated in Intellectual developmental disorder, autosomal recessive 6, and Neurodevelopmental disorder with impaired language and ataxia, both characterized by developmental delays and intellectual challenges. Understanding the role of Glutamate receptor ionotropic, kainate 2 could open doors to potential therapeutic strategies for these neurological conditions.
