2. AI-Driven Conformational Ensemble Generation
Starting from the initial protein structure, we employed advanced AI algorithms to predict alternative functional states of High affinity copper uptake protein 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:
High affinity copper uptake protein 1, also known as Copper transporter 1 (SLC31A1), plays a pivotal role in copper homeostasis. It facilitates the transport of copper(1+) across the plasma membrane, directly influencing intracellular copper levels. This protein also engages in the transport of other metals such as silver(1+) and cadmium(2+), and participates in copper(2+) acquisition, showcasing its versatility in metal ion transport. Additionally, SLC31A1 acts as a redox sensor, promoting angiogenesis independently of its copper transport function.
Therapeutic significance:
SLC31A1's dysfunction is linked to neurodegeneration and seizures due to copper transport defect, a severe autosomal recessive disorder. Understanding the role of High affinity copper uptake protein 1 could open doors to potential therapeutic strategies, especially in targeting copper metabolism disorders and enhancing drug delivery for chemotherapeutic agents.
