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 Cilia- and flagella-associated protein 52 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 Cilia- and flagella-associated protein 52 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 Cilia- and flagella-associated protein 52, 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:
Cilia- and flagella-associated protein 52, also known as WD repeat-containing protein 16, plays a crucial role in the structure and function of cilia and flagella. This protein is a part of the microtubule inner protein complex, essential for the proper beating of cilia and flagella, and is implicated in cell growth and survival. Its interaction with CFAP45 and DNAH11 underscores its significance in cellular motility mechanisms.
Therapeutic significance:
The association of Cilia- and flagella-associated protein 52 with Heterotaxy, visceral, 10, autosomal, with male infertility, highlights its potential as a therapeutic target. Understanding the role of this protein could open doors to potential therapeutic strategies for treating congenital defects and male infertility linked to ciliary dysfunction.
