It is produced by decarboxylation of an amino acid and the liver deactivates any that circulates through methylation and oxidation reactions.

It causes phosphorylation of an intercellular adhesion protein, creating gaps between cells into which fluids can seep and may also cause leukocytes to release cytokines. Appearing after IgE brings a response from a mast cell, it also causes constriction of smooth muscle, so its release brings on asthma attacks when triggering substances appear.
