G protein-coupled octopamine receptors of insects and other invertebrates represent counterparts of adrenoceptors in vertebrate animals. The alpha(2)-adrenoceptor agonist medetomidine, which is in clinical use as a veterinary sedative agent, was discovered to inhibit the settling process of barnacles, an important step in the ontogeny of this crustacean(More)
INTRODUCTION Phosphorylation of myosin light chains is a biochemical readout of smooth muscle cell contraction. α2-Adrenoceptor agonists and antagonists may have important applications in cardiovascular drug development. To assess α2-adrenoceptor-mediated drug effects on vascular smooth muscle contraction, we developed a cell-based assay for the(More)
The high affinity transporters for the monoamine neurotransmitters, dopamine, norepinephrine, and serotonin, play a key role in controlling monoaminergic neurotransmission. It is believed that the transporters (DAT, NET and SERT, respectively) are subject to tight regulation by the cellular signaling machinery to maintain monoaminergic homeostasis. Kinases(More)
The norepinephrine transporter (NET) mediates reuptake of synaptically released norepinephrine in central and peripheral noradrenergic neurons. The molecular processes governing availability of NET in the plasma membrane are poorly understood. Here we use the fluorescent cocaine analogue JHC 1-64, as well as several other approaches, to investigate the(More)
