Caloxin 1b3

Caloxin 1b3, a peptide, is a selective plasma membrane Ca2+ pump 1 (PMCA1) inhibitor. Caloxin 1b3 significantly inhibits PMCA1 Ca2+–Mg2+-ATPase in the rabbit duodenal mucosa than the PMCA4 in the human erythrocyte ghosts. Caloxin 1b3 also increases cytosolic Ca2+ concentration in endothelial cells. Caloxin 1b3 can be used for cardiovascular disorders research[1].
