This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Probable phospholipid-transporting ATPase IIA 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 Probable phospholipid-transporting ATPase IIA 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 Probable phospholipid-transporting ATPase IIA, 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 Probable phospholipid-transporting ATPase IIA, also known as ATPase class II type 9A, is pivotal in regulating membrane trafficking, including endosome to plasma membrane recycling and endosome to trans-Golgi network retrograde transport. It activates RAB5 and RAB11, and in complex with MON2 and DOP1B, it oversees SNX3 retromer-mediated endosomal sorting of WLS, crucial for Wnt morphogen transport in development. Additionally, it plays a role in intercellular communication by modulating exosome release and is essential for maintaining neurite morphology and synaptic transmission.
Therapeutic significance:
Linked to a neurodevelopmental disorder characterized by developmental delay, intellectual impairment, and behavioral abnormalities, understanding the role of Probable phospholipid-transporting ATPase IIA could open doors to potential therapeutic strategies.
