Cyclic AMP-Rap1A signaling activates RhoA to induce α2c-adrenoceptor translocation to the cell surface of microvascular smooth muscle cells
( American Physiological Society , 2012 , Article)Intracellular signaling by the second messenger cyclic AMP (cAMP) activates the Ras-related small GTPase Rap1 through the guanine exchange factor Epac. This activation leads to effector protein interactions, activation, ... -
Cyclic AMP-Rap1A signaling mediates cell surface translocation of microvascular smooth muscle α2C-adrenoceptors through the actin-binding protein filamin-2
( American Physiological Society , 2013 , Article)The second messenger cyclic AMP (cAMP) plays a vital role in vascular physiology, including vasodilation of large blood vessels. We recently demonstrated cAMP activation of Epac-Rap1A and RhoA-Rho-associated kinase ... -
