This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Microtubule-associated protein tau 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 Microtubule-associated protein tau 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 Microtubule-associated protein tau, 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:
Microtubule-associated protein tau, known as Neurofibrillary tangle protein or Paired helical filament-tau, plays a pivotal role in promoting microtubule assembly and stability. It is crucial in neuronal polarity establishment and maintenance, acting as a linker between axonal microtubules and neural plasma membrane components. The protein's localization influences axonal polarity, with its isoforms affecting cytoskeleton plasticity and stabilization.
Therapeutic significance:
Tau is implicated in several neurodegenerative diseases, including Frontotemporal dementia, Pick disease of the brain, Progressive supranuclear palsy 1, and Parkinson-dementia syndrome. These conditions are characterized by cognitive decline, memory loss, and motor symptoms, with tau pathology being a common hallmark. Understanding the role of tau in these diseases could lead to novel therapeutic strategies targeting tau pathology to alleviate or halt disease progression.
