Therefore, calcium seemed to be a required fundamental co-factor underlying all biological membrane-fusion steps, perhaps with a conserved mechanism of action. However, although such unification would be gratifying, new data indicate that several intracellular fusion events do not require calcium after all.

Regulation of Growth Cone Behavior by Calcium

Intracellular calcium levels can be significantly raised by the application of the calcium ionophore A23187 to the growth medium. Direct measurements of intracellular calcium show that low to moderate doses of A23 187 do produce a substantial rise in intracellular calcium levels. In many cells, however, this rise is transient; intracellular ...

Regulation of Intracellular Free Calcium | SpringerLink

Abstract. It can be argued that the calcium ion is the oldest recognized signal transduction molecule, whether one dates the birth of this recognition with Ringer’s 1883 studies 1 on the requirement for extracellular Ca 2+ in myocardial contraction, or with Heilbrunn’s much later proposal 2 that Ca 2+ is the physiological inducer of muscle contraction. . Perhaps because of this early focus ...
