Regulation of the state of phosphorylation of specific neuronal proteins in mouse brain by in vivo administration of anesthetic and convulsant agents.
The effect of drug treatment in vivo on the state of phosphorylation of two specific neuronal proteins, proteins Ia and Ib, has been studied in mouse brain. For this purpose, animals were killed by immersion into liquid nitrogen, and proteins Ia and Ib were extracted by a procedure designed to prevent alterations in their state of phosphorylation. Several anesthetic agents (pentobarbital, chloral hydrate, and urethane) each caused a decrease in the state of phosphorylation of these proteins. Conversely, the convulsant agents pentylenetetrazol and picrotoxin each caused an increase in the state of phosphorylation of these proteins. Neither the anesthetic nor the convulsant agents affected the total amount of these proteins. The results are compatible with a role for proteins Ia and Ib in neuronal function.
