Glucagon (19 - 29), bovine,human, porcine

Glucagon (19-29), aka miniglucagon, the C-terminal (19-29) fragment inhibited both the Ca2+ activated and Mg2+ dependent ATPase activity and Ca2+ transport in liver plasma membranes with an efficiency 1000-fold higher than that of glucagon. It is likely to be the active peptide involved in the inhibition of the liver Ca2+ pump.
