Neuronal calcium sensor-1 and phosphatidylinositol 4-kinase beta stimulate extracellular signal-regulated kinase 1/2 signaling by accelerating recycling through the endocytic recycling compartment.

Abstract

We demonstrate that recycling through the endocytic recycling compartment (ERC) is an essential step in Fc epsilonRI-induced activation of extracellular signal-regulated kinase (ERK)1/2. We show that ERK1/2 acquires perinuclear localization and colocalizes with Rab 11 and internalized transferrin in Fc epsilonRI-activated cells. Moreover, a close… (More)
