Proenkephalin (PENK), formerly known as proenkephalin A (since proenkephalin B was renamed prodynorphin), is an endogenous opioid polypeptide hormone which, via proteolyic cleavage, produces the enkephalin peptides [Met]enkephalin, and to a lesser extent, [Leu]enkephalin. Upon cleavage, each proenkephalin peptide results in the generation of four copies of [Met]enkephalin, two extended copies of [Met]enkephalin, and one copy of [Leu]enkephalin.
