General description

Octopamine is a biogenic amine, which functions as a neurotransmitter, neuromodulator and neurohormone. It is used to regulate various behaviors, such as learning, memory and aggression. Octopamine is present in mammalian tissues, human urine and invertebrates.

Application

(±)-Octopamine hydrochloride has been used:
  • for neurotransmitter assays
  • to rupture the encased oocyte into the oviduct
  • to specifically induce dramatic assembly of reflectin
  • to identify central octopamine receptor-expressing neurons (OARNs) involved in aggression in Drosophila

Biochem/physiol Actions

α-adrenoceptor agonist; invertebrate neurotransmitter.

Octopamine (OA), a biogenic monoamine structurally related to noradrenaline, acts as a neurohormone, a neuromodulator and a neurotransmitter in invertebrates. It is present in relatively high concentrations in neuronal as well as in non-neuronal tissues of most invertebrate species studied.
