Description: The molecule is a polypeptide consisting of 31 amino acid residues in the sequence Tyr-Gly-Gly-Phe-Met-Thr-Ser-Glu-Lys-Ser-Gln-Thr-Pro-Leu-Val-Thr-Leu-Phe-Lys-Asn-Ala-Ile-Ile-Lys-Asn-Ala-Tyr-Lys-Lys-Gly-Glu. It is an endogenous opioid peptide neurotransmitter found in the neurons of both the central and peripheral nervous system and results from processing of the precursor protein proopiomelanocortin (POMC). It has a role as a neurotransmitter.
