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 Cation channel sperm-associated targeting subunit tau 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 Cation channel sperm-associated targeting subunit tau 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 Cation channel sperm-associated targeting subunit tau, 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 Cation channel sperm-associated targeting subunit tau, also known as Amyotrophic lateral sclerosis 2 chromosomal region candidate gene 11 protein and C2 calcium-dependent domain-containing protein 6, plays a crucial role in sperm cell hyperactivation. This process is essential for sperm motility, a key factor in the successful fertilization of an egg. The protein is an auxiliary component of the CatSper complex, facilitating the targeting and trafficking of this complex into the quadrilinear nanodomains of elongating flagella.
Therapeutic significance:
Spermatogenic failure 68, a disorder characterized by globozoospermia and linked to variants affecting this protein, highlights its critical role in male fertility. Understanding the role of Cation channel sperm-associated targeting subunit tau could open doors to potential therapeutic strategies for treating infertility issues related to sperm motility.
