...Renato C. Nogueira; Lucia de Fatima S. Sampaio ABSTRACT Calmodulin is vital for chick embryos morphogenesis in the incubation time 48–66 h when the rudimentary C-shaped heart attains an S-shaped pattern and the optic vesicles develop into optic cups. Melatonin is in the extraembryonic yolk sac...

...) inhibitor H-89 or the calmodulin (CaM) inhibitor calmidazolium. A complete inhibition of hypertonic- and acidification-induced changes of pHi concurrent with an increase in hypertonically induced proton efflux was seen with the protein kinase C (PKC) inhibitor chelerythrine. Recovery of pHi following sodium...

... and calmidazolium both block CBF excitation by caffeine and dopamine, and W-7 is effective at blocking TPep-NLS excitation. The effects of calmidazolium and W-7 suggest a role for Ca 2+ -calmodulin in regulating CBF, either directly or via Ca 2+ -calmodulin dependent kinases or phosphodiesterases. From...

... into the vacuole and secretory organelles, respectively. The function of either Ca 2+ pump is sufficient for yeast viability, but deletion of both genes is lethal because of elevation of cytosolic [Ca 2+ ] and activation of calcineurin, a Ca 2+ -and calmodulin-dependent protein phosphatase. Calcineurin activation...
