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 PR domain zinc finger protein 13 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 PR domain zinc finger protein 13 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 PR domain zinc finger protein 13, 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:
PR domain zinc finger protein 13, alternatively known as PR domain-containing protein 13, plays a pivotal role in the human body. It is involved in transcriptional regulation and is essential for the differentiation of KISS1-expressing neurons in the hypothalamus. Furthermore, it acts as a critical regulator of GABAergic cell fate in the cerebellum, ensuring normal postnatal development.
Therapeutic significance:
The protein is linked to severe neurological disorders, including cerebellar dysfunction with impaired intellectual development and hypogonadotropic hypogonadism, and pontocerebellar hypoplasia 17. These associations highlight its potential as a target for therapeutic intervention in these debilitating conditions.
