Caloxin 2A1 TFA is an extracellular plasma membrane Ca2+-ATPase (PMCA) peptide inhibitor. Caloxin 2A1 TFA does not affect basal Mg2+-ATPase or Na+-K+-ATPase[1].
Caloxin 2A1 TFA inhibits Ca2+-Mg2+-ATPase in human erythrocyte leaky ghosts, but it does not affect basal Mg2+-ATPase or Na+-K+-ATPase in the ghosts or Ca2+-Mg2+-ATPase in the skeletal muscle sarcoplasmic reticulum. Caloxin 2A1 TFA also inhibits Ca2+-dependent formation of the 140-kDa acid-stable acylphosphate[1].
Caloxin 2A1 TFA increases airway smooth muscle cells (ASMCs) apoptosis[2].
