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 Lysine-specific demethylase 5C 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 Lysine-specific demethylase 5C 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 Lysine-specific demethylase 5C, 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:
Lysine-specific demethylase 5C, known as Histone demethylase JARID1C, plays a pivotal role in histone code by specifically demethylating 'Lys-4' of histone H3. This action does not extend to other lysine sites on histone H3 or H4, highlighting its specificity. It is involved in transcriptional repression of neuronal genes, crucial for maintaining neuron-restrictive silencer elements.
Therapeutic significance:
The protein's mutation is linked to Intellectual developmental disorder, X-linked, syndromic, Claes-Jensen type, characterized by intellectual disability and potentially progressive spastic paraplegia. Understanding the role of Lysine-specific demethylase 5C could open doors to potential therapeutic strategies for this disorder.
