Complement component C8 alpha chain - 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 Complement component C8 alpha chain 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 Complement component C8 alpha chain 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 Complement component C8 alpha chain, 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 Complement component C8 alpha chain, also known as Complement component 8 subunit alpha, is a crucial part of the membrane attack complex (MAC). This complex plays a pivotal role in both innate and adaptive immunity by forming pores in the plasma membrane of target cells, leading to cell lysis. The C8A subunit, encoded by the gene with accession number P07357, is essential for inserting into the target membrane, although it does not form pores by itself.

Therapeutic significance:

Complement component 8 deficiency, 1, a rare disease linked to this protein, results in increased susceptibility to severe recurrent infections, especially by Neisseria species. Understanding the role of Complement component C8 alpha chain could open doors to potential therapeutic strategies for enhancing immune response and preventing these infections.
