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 Dynein regulatory complex subunit 2 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 Dynein regulatory complex subunit 2 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 Dynein regulatory complex subunit 2, 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:
Dynein regulatory complex subunit 2, also known as Coiled-coil domain-containing protein 65 or Testis development protein NYD-SP28, plays a pivotal role in ciliary and flagellar motility. It is a crucial component of the nexin-dynein regulatory complex (N-DRC), ensuring the proper alignment and integrity of the distal axoneme. This protein is instrumental in the assembly of N-DRC, stabilizing the inner dynein arms and radial spokes, and facilitating their attachment to outer doublet microtubules.
Therapeutic significance:
The protein's involvement in primary ciliary dyskinesia, particularly type 27, underscores its therapeutic significance. This condition, characterized by motile cilia abnormalities, leads to chronic respiratory infections and potentially situs inversus in Kartagener syndrome. Understanding the role of Dynein regulatory complex subunit 2 could open doors to potential therapeutic strategies for treating or managing these ciliary disorders.
