Cyclic nucleotides, phosphorylated proteins, and the nervous system.
Some postsynaptic effects of several classes of neurotransmitters appear to be mediated or modulated through the cyclic nucleotides, cyclic AMP and cyclic GMP. Available evidence suggests that the molecular mechanism by which the cyclic nucleotides carry out this second messenger role in nerve cells involves regulation of the state of phosphorylation of specific neuronal proteins. Phosphorylated proteins also appear to be involved in mediating certain of the actions of several other classes of regulatory agents, including calcium and the steroid hormones.
