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 AP-3 complex subunit delta-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 AP-3 complex subunit delta-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 AP-3 complex subunit delta-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:
The AP-3 complex subunit delta-1, also known as Adaptor-related protein complex 3 subunit delta-1 or Delta-adaptin, plays a crucial role in the trafficking of vesicles from the Golgi membrane, potentially directing them towards lysosomes. It is integral to the process of CD8+ T-cell and NK cell degranulation and works alongside the BLOC-1 complex to ensure proper cargo delivery into neurites and nerve terminals.
Therapeutic significance:
Given its involvement in Hermansky-Pudlak syndrome 10, a disorder characterized by albinism, neutropenia, and immunodeficiency, understanding the role of AP-3 complex subunit delta-1 could open doors to potential therapeutic strategies. Its function in vesicle trafficking and immune cell degranulation highlights its potential as a target for therapeutic intervention in related diseases.
