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 Tripartite motif-containing protein 2 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 Tripartite motif-containing protein 2 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 Tripartite motif-containing protein 2, 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:
Tripartite motif-containing protein 2 (TRIM2), also known as E3 ubiquitin-protein ligase TRIM2 or RING finger protein 86, plays a pivotal role in the nervous system. It is involved in the UBE2D1-dependent ubiquitination of NEFL and phosphorylated BCL2L11, contributing to neuroprotection and neuronal rapid ischemic tolerance. Additionally, TRIM2 has a role in antiviral immunity, particularly against New World arenavirus infections.
Therapeutic significance:
TRIM2's involvement in Charcot-Marie-Tooth disease, axonal, 2R, a peripheral nervous system disorder characterized by muscle weakness and atrophy, highlights its therapeutic potential. Understanding TRIM2's function could lead to novel treatments for this and related neuropathies.
