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 Visual system homeobox 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 Visual system homeobox 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 Visual system homeobox 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:
Visual system homeobox 2 (VSX2), also known as Homeobox protein CHX10, plays a pivotal role in eye development and function. It acts as a transcriptional regulator, binding to DNA to influence gene expression. VSX2 is crucial for the morphogenesis of the sensory retina, differentiation of V2a interneurons, and the development of retinal ganglion cells, which are essential for vision.
Therapeutic significance:
VSX2 is implicated in several eye formation disorders, including Microphthalmia, isolated, 2, Microphthalmia with cataracts and iris abnormalities, and Microphthalmia, isolated, with coloboma, 3. These conditions range from minor eye size anomalies to complete absence of ocular tissues. Understanding the role of VSX2 could open doors to potential therapeutic strategies for these visual impairments.
