title: Deltamethrin causes changes in protein phosphorylation activities associated with post-depolarization events in the synaptosomes from the optic lobe of squid, Loligo pealei.
abstract: 1. Deltamethrin causes a significant change in protein phosphorylation activities which follow depolarization. 2. The most significant change caused by deltamethrin was the prolonged elevation of the level of phosphorylation on a number of key synaptic proteins beyond the normal time of their recovery to the dephosphorylated state. 3. The best marker proteins reacting to deltamethrin in this manner were calcium-calmodulin dependent protein kinase and synapsin I.
