Structure of the thrombopoietin-MPL receptor complex is a blueprint for biasing hematopoiesis

PROJECT OVERVIEW

In this project we solved the structure of the thrombopoietin receptor MPL. Thrombopoietin (TPO) is a master regulator of haematopoiesis and using this structural knowledge we designed new modified TPOs to control haematopoeisis.

Abstract

The thrombopoietin-MPL axis plays essential roles in hematopoietic stem cell biology and platelet production. Cryo-EM structure of the dimeric thrombopoietin- MPL receptor complex enabled design of biased agonists that tune intracellular signaling, thereby uncoupling the primary opposing functions of thrombopoietin signaling, hematopoietic stem cell maintenance, and differentiation.
