BPI fold-containing family A member 1 - Focused Library Design

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 BPI fold-containing family A member 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 BPI fold-containing family A member 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 BPI fold-containing family A member 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:

BPI fold-containing family A member 1, known for its alternative names such as Lung-specific protein X and Secretory protein in upper respiratory tracts, is a lipid-binding protein with high specificity for DPPC. It plays a crucial role in the innate immune responses of the upper airways, reducing surface tension in airway secretions and inhibiting biofilm formation by Gram-negative bacteria. Additionally, it regulates the cleavage of SCNN1G, contributing to airway surface liquid homeostasis and mucus clearance.

Therapeutic significance:

Understanding the role of BPI fold-containing family A member 1 could open doors to potential therapeutic strategies. Its involvement in airway immune responses and mucus clearance highlights its potential as a target for treating respiratory conditions.
