Phosphorylation of Rab-coupling protein by LMTK3 controls Rab14-dependent EphA2 trafficking to promote cell:cell repulsion

Abstract

Ephrin receptors mediate contact inhibition, but their intracellular trafficking during this process is unknown. Here the authors show that EphA2 receptor trafficking is regulated by the Rab GTPase effector Rab-coupling protein, which associates with Rab14-endosomes upon LMTK3-mediated phosphorylation.
