Abstract
We describe methods based on live cell fluorescent microscopy and mass spectrometry to characterize the mechanism of endosomal cAMP production and its regulation using the parathyroid hormone (PTH) type 1 receptor as a prime example. These methods permit to measure rapid changes of cAMP levels in response to PTH, kinetics of endosomal ligand-receptor interaction, pH changes associated with receptor trafficking, and to identify the endosomal receptor interactome.Entities:
