This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Transmembrane protein 43 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 protein 43 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 protein 43, 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 protein 43, also known as Protein LUMA, plays a pivotal role in maintaining nuclear envelope structure and organizing protein complexes at the inner nuclear membrane. It is essential for retaining emerin at the inner nuclear membrane and modulates innate immune signaling through the cGAS-STING pathway. Additionally, it acts as a critical signaling component in NF-kappa-B activation, positioned downstream of EGFR and upstream of CARD10. It also contributes to passive conductance current in cochlear glia-like supporting cells, necessary for hearing and speech discrimination.
Therapeutic significance:
Transmembrane protein 43 is implicated in several diseases, including Arrhythmogenic right ventricular dysplasia, familial, 5, Emery-Dreifuss muscular dystrophy 7, autosomal dominant, and Auditory neuropathy, autosomal dominant 3. These associations highlight its potential as a target for therapeutic strategies aimed at treating congenital heart disease, degenerative myopathies, and sensorineural hearing loss.
