Octopamine as the transmitter at the firefly lantern: Presence of an octopamine-sensitive and a dopamine-sensitive adenylate cyclase

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1982
Abstract 1. Both octopamine and dopamine cause a large increase in synthesis of cyclic AMP in the lantern of the fireflies Photuris versicolor and Photuris lucicrescens . 2. Lanterns were much more sensitive to octopamine than to dopamine. 3.

Photoaffinity Labeling of a Neuronal Octopamine Receptor

Journal of Neurochemistry, 1994
Abstract: The invertebrate aminergic neurotransmitter and neuromodulator octopamine (OA) acts at both neuronal and nonneuronal receptors that appear to have distinct pharmacological characteristics. The current work uses a potent and specific OA photoaffinity ligand, tritiated 2(2,6‐diethyl‐4‐azidophenylimino)imidazolidine ([3H]NC‐5Z), to identify and ...

ACTION OF OCTOPAMINE AGONISTS AND STEREO ISOMERS AT A SPECIFIC OCTOPAMINE RECEPTOR

Clinical and Experimental Pharmacology and Physiology, 1978
SUMMARY1. (±)‐Octopamine, (±)‐N‐methyl octopamine and (‐)‐α‐methyl octopamine increase the amplitude of contraction of the spontaneously beating ventricle of the mollusc Tapes watlingi through action on a specific octopamine receptor.2. Unlike the excitatory responses to dopamine, noradrenaline or serotonin, the excitatory response of the ventricle to ...

A new octopamine receptor class in locust nervous tissue, the octopamine 3 (OA3) receptor

Life Sciences, 1992
The insect neuronal 3H-octopamine binding site represents a new type of octopamine receptor. This receptor has pharmacological features that are characteristic for all known octopamine receptors, but it is possible to distinguish this receptor class from all others using either agonists or antagonists.

Octopamine as a putative neurotransmitter.

Advances in biochemical psychopharmacology, 1977
Octopamine is a normally occurring amine in nervous tissues in many species of animals. In mammals, octopamine is formed from tyramine through beta-hydroxylation by DBH in the sympathetic nerves, and it is partially stored in nerve endings with a subcellular distribution similar to that of NE.
