Glucagon. The glucagon receptor is widely expressed and can be found in the liver, adipose tissue, heart, kidney, pancreatic islets, stomach, small intestine, thyroid, and skeletal muscle.

NMDA receptors are blocked by magnesium during cell hyperpolarization, and allow Ca influx when the cell is depolarized.
