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 WD repeat-containing protein 35 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 WD repeat-containing protein 35 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 WD repeat-containing protein 35, 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:
WD repeat-containing protein 35, also known as Intraflagellar transport protein 121 homolog, plays a crucial role in ciliogenesis and ciliary protein trafficking. It is a part of the IFT complex A, essential for retrograde ciliary transport and the entry of G protein-coupled receptors into cilia. This protein's involvement in CASP3 activation and TNF-stimulated apoptosis highlights its multifaceted role in cellular processes.
Therapeutic significance:
WD repeat-containing protein 35 is implicated in several genetic disorders, including Cranioectodermal dysplasia 2 and Short-rib thoracic dysplasia 7, both characterized by skeletal and ectodermal abnormalities. Understanding the role of this protein could open doors to potential therapeutic strategies for these ciliopathies, emphasizing the importance of targeted research in this area.
