AI-ACCELERATED DRUG DISCOVERY
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 Cell cycle control protein 50B 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 Cell cycle control protein 50B 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 Cell cycle control protein 50B, 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.

UPID:
CC50B_HUMAN
Alternative names:
P4-ATPase flippase complex beta subunit TMEM30B; Transmembrane protein 30B
Alternative UPACC:
Q3MIR4; B3KR84; Q14D00
Background:
Cell cycle control protein 50B, also known as TMEM30B, is a critical component of the P4-ATPase flippase complex. This complex plays a pivotal role in maintaining the asymmetric distribution of phospholipids across membranes by transporting aminophospholipids from the outer to the inner leaflet. This process is essential for vesicle formation and the uptake of lipid signaling molecules, with TMEM30B assisting in substrate binding and facilitating the export of alpha subunits from the ER to the plasma membrane.
Therapeutic significance:
Understanding the role of Cell cycle control protein 50B could open doors to potential therapeutic strategies. Its involvement in phospholipid translocation and membrane asymmetry is fundamental to cellular processes, suggesting that modulation of its activity could have therapeutic implications.
