Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

The calcitonin gene related peptide (yellow) binds to its receptor (blue) on neurons and smooth muscle cells of cerebral blood vessels, activating a signal cascade through G-proteins (dark blue) in this cells that  leads to a dilatation of the blood vessels (vasodilatation). Blocking the CGRP receptor diminishes the quantity of migraine attacks.\
