synaptoPAC
Multi-Component SwitchsynaptoPAC is a presynaptically targeted version of the photoactivated adenylyl cyclase bPAC developed as a light-responsive optogenetic tool for induction of presynaptic plasticity. It is reported to increase action potential-evoked transmission in some neuronal contexts, but this potentiation was not observed in non-granule hippocampal cultures or at Schaffer collateral synapses in CA1 acute slices.
