VMAT1 (Vesicular monoamine transporter 1) is a protein that transports the monoamine neurotransmitters into synaptic vesicles.
In chromaffin cells, it is responsible for transporting newly synthesized epinephrine from the cytosol back into chromaffin granules in preparation for release.
For norepinephrine to be acted upon by PNMT in the cytosol, it must first be shipped out of granules of the chromaffin cells. This may occur via the catecholamine-H+ exchanger VMAT1.
