General description

α-Endorphin is one of the three endorphins found in the brain, which has morphine-mimetic activities. It is a hexadecapeptide with a primary structure of H-Tyr-Gly-Gly-Phe-Met-Thr-Ser-Glu-Lys-SerGln-Thr-Pro-Leu-Val-Thr-OH. It is a fragment of β-Endorphin (β-LPH61-91), which is an endogenous opioid ligand, and is denoted as (β-LPH61-76). It is found in the hypothalamus and pituitary.

Biochem/physiol Actions

α-Endorphin is a substrate for transglutaminase, and has stimulatory effects on immune system function. It influences the self-stimulating tendencies in rat, related to electrical stimulation of the ventral tegmentum area neurons. It counteracts the effect of γ-endorphin and promotes this behavior in rats. The functionality of α-endorphin is comparable to that of psychostimulant drugs, and as it acts in an opposing manner to γ-endorphin, these peptides might have a central role in the homeostasis of brain function.

beta-Endorphin (beta-LPH61-91) is a well known endogenous opioid ligand. It and related peptides have recently been implicated in the control of adaptive behaviour. Smaller beta-endorphin fragments appeared to be more active moieties than the parent molecule in a number of
