This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Abscission/NoCut checkpoint regulator 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 Abscission/NoCut checkpoint regulator 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 Abscission/NoCut checkpoint regulator, 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 Abscission/NoCut checkpoint regulator, also known as Zinc finger FYVE domain-containing protein 19, plays a pivotal role in cytokinesis. It ensures the proper timing of abscission, preventing premature resolution of intercellular chromosome bridges and DNA damage accumulation. This protein, alongside CHMP4C, maintains VPS4 at the midbody ring until the abscission checkpoint signaling concludes.
Therapeutic significance:
Linked to Cholestasis, progressive familial intrahepatic, 9 (PFIC9), a severe liver disorder, understanding the Abscission/NoCut checkpoint regulator's role could unveil new therapeutic avenues. The PFIC9-associated variant p.M76V suggests a direct impact on protein function, highlighting its potential as a therapeutic target.
