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 Mitochondrial ribonuclease P catalytic subunit 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 Mitochondrial ribonuclease P catalytic subunit 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 Mitochondrial ribonuclease P catalytic subunit, 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:
The Mitochondrial ribonuclease P catalytic subunit, also known as Protein only RNase P catalytic subunit, plays a pivotal role in mitochondrial RNA processing. It is a key component of the mitochondrial ribonuclease P complex, essential for cleaving tRNA molecules at their 5'-ends, a critical step in the maturation of mitochondrial tRNAs. This protein's function underscores its importance in mitochondrial transcription and translation, processes vital for cellular energy production.
Therapeutic significance:
Combined oxidative phosphorylation deficiency 54, a multisystem disorder with variable manifestations including sensorineural hearing loss and muscle weakness, is linked to mutations affecting this protein. Understanding the role of the Mitochondrial ribonuclease P catalytic subunit could open doors to potential therapeutic strategies for this and related mitochondrial disorders.
