This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Transmembrane 4 L6 family member 20 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 Transmembrane 4 L6 family member 20 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 Transmembrane 4 L6 family member 20, 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:
Transmembrane 4 L6 family member 20 (TM4SF20) is a polytopic transmembrane protein known for its role in inhibiting the regulated intramembrane proteolysis (RIP) of CREB3L1, thus preventing collagen synthesis activation. This process is influenced by ceramide, which can alter TM4SF20's membrane topology and stimulate CREB3L1's RIP activation. The unique 'regulated alternative translocation' (RAT) mechanism is pivotal in TM4SF20's function, showcasing its complex role in cellular processes.
Therapeutic significance:
TM4SF20's involvement in Specific language impairment 5, a disorder marked by delayed speech acquisition and potential cerebral abnormalities, underscores its clinical relevance. Understanding TM4SF20's function could pave the way for innovative therapeutic strategies targeting speech and developmental disorders, offering hope for affected individuals.
