We have examined a possible role for Ca ( 2+ ) /CaM in modulating both the binding of guanine nucleotides to Rab3A and the GTPase activity of Rab3A ... The basal level of Rab3A GTPase activity was not affected by an association with Ca ( 2+ ) /CaM Park et al., J Biol Chem 1997

We demonstrate here that Ca2+/calmodulin also can cause Rab3A to dissociate from synaptic membranes in vitro
