Both hGPR1 and mGPR1 Activate MAP Kinases ERK1/2 We tested whether the constitutive interaction of mGPR1 with -arrestins modifies the of mGPR1 with -arrestins modifies We tested irrespective of whether the constitutive subcellular localization of -arrestins by measuring the BRET signal among -arrestinsthe subcellular localization of -arrestins by measuring the BRET signal amongst -arRLuc and and KRas-Venus. In expressing mGPR1, -arrestins partially localize for the restins-RLucKRas-Venus. In cellscells expressing mGPR1, -arrestins partially localize to plasma membrane in in basal situations (Figure five).
