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 Megakaryocyte and platelet inhibitory receptor G6b 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 Megakaryocyte and platelet inhibitory receptor G6b 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 Megakaryocyte and platelet inhibitory receptor G6b, 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:
Megakaryocyte and platelet inhibitory receptor G6b, also known as Protein G6b, plays a pivotal role in hematopoietic lineage differentiation, megakaryocyte function, and platelet production. It inhibits platelet aggregation and activation through its unique structure, featuring a transmembrane region and two immunoreceptor tyrosine-based inhibitor motifs (ITIMs). This protein operates in a calcium-independent manner, regulating megakaryocyte function and platelet production by inhibiting CLEC1B and GP6:FcRgamma signaling pathways.
Therapeutic significance:
Given its critical role in regulating platelet production and function, Megakaryocyte and platelet inhibitory receptor G6b is directly linked to thrombocytopenia, anemia, and myelofibrosis. Understanding the role of this protein could open doors to potential therapeutic strategies for these conditions, offering hope for patients suffering from these debilitating diseases.
