The present study aims to define the downstream signaling cascade initiated by the PI-linked dopamine receptor. Incubation of rat brain frontal cortical slices with 6-chloro-7,8-dihydroxy-3-methyl-1-(3-methylphenyl)-2,3,4,5-tetrahydro-1H-3-benzazepine (SKF83959), a recently identified selective agonist of the PI-linked D1-like dopamine receptor, elicited transient time- and dose-dependent stimulations of cyclin-dependent kinase 5 (cdk5) and calcium/calmodulin-dependent protein kinase II (CaMK II) activities. The stimulation of these kinases is blocked by 20 microM R-(+)-7-chloro-8-hydroxy-3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine (SCH23390) or the PLCbeta antagonist 1-[6-[[17beta-methoxyestra-1,3,5(10)-trien-17-yl]amino]hexyl]-1H-pyrrole-2,5-dione (U-73122) and is attenuated by the protein kinase inhibitor calphostin C or by the intracellular calcium chelator BAPTA, indicating that SKF83959 stimulates cdk5 and CaMK II activities via a PI-linked D1-like dopamine receptor, and PLCbeta and is dependent on protein kinase C and calcium. Although cdk5 and CaMK II are physically associated in native brain tissue, no change in this association was observed in response to SKF83959 stimulation or to the inhibition of either cdk5 by roscovitine or of CaMK by 2-[N-(2-hydroxyethyl)]-N-(4-methoxybenzenesulfonyl)]amino-N-(4-chlorocinnamyl)-N-methylbenzylamine) (KN93), suggesting that SKF83959-mediated stimulation of cdk5 or CaMK II is independent of the other kinase and that the association of the two kinases is not modulated by change of kinase activity. Moreover, we found that cdk5 phosphorylates dopamine and cAMP-regulated phosphoprotein at Thr75, whereas CaMK II is responsible for the activation of cAMP response element-binding protein in response to SKF83959 stimulation. The present data provide the first insight into the signaling mechanism for the PI-linked dopamine receptor. This information, in turn, may help in exploring the functional consequences of stimulation of this brain receptor."xsd:string |
