Amidorphin is an

mammalian brain, with particularly high concentrations found in the striatum, and outside of the brain in adrenal medulla and posterior pituitary.[1][2]
The 26-residue peptide named amidorphin is found in several species including bovine (Bos taurus), sheep (Ovis aries), and pig (Sus scrofa). Humans and commonly studied lab animals (mice, rats) produce a 27-residue peptide that does not have an amidated C-terminal residue; this is due to the absence of a Gly in the precursor sequence and replacement with Ala, which is not a substrate for the amidating enzyme (Peptidyl-glycine alpha-amidating monooxygenase). The properties of the 27-residue peptide are presumably similar to those of amidorphin, although this has not been adequately tested.

In some brain areas, amidorphin is extensively further reduced into smaller fragments, such as the non-opioid peptide

sequence of amidorphin.[3]
