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 COUP transcription factor 1 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 COUP transcription factor 1 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 COUP transcription factor 1, 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:
COUP transcription factor 1, also known as Nuclear receptor subfamily 2 group F member 1, plays a pivotal role in gene expression regulation. It binds to the ovalbumin promoter, stimulating transcription initiation in conjunction with S300-II. This protein's ability to bind both direct repeats and palindromes of the 5'-AGGTCA-3' motif showcases its versatility in gene regulation.
Therapeutic significance:
Linked to Bosch-Boonstra-Schaaf optic atrophy syndrome, a disorder marked by optic atrophy, developmental delay, and intellectual disability, COUP transcription factor 1's study could lead to novel therapeutic avenues. Understanding its role in cerebral visual impairment offers a promising pathway for targeted treatment strategies.
