A cDNA encoding a high-affinity Na(+)/anion(-)-dependent octopamine transporter (OAT) was isolated via an RT-PCR-based approach from caterpillars of the cabbage looper, Trichoplusia ni. The deduced amino acid sequence of the OAT cDNA predicts a 670 amino acid protein bearing strong homology to
A cDNA was cloned from the cabbage looper Trichoplusia ni based on similarity to other cloned dopamine transporters (DATs). The total nucleotide sequence is 3.8 kb in length and contains an open reading frame for a protein of 612 amino acids. The predicted moth DAT protein (TrnDAT) has greatest
The invertebrate octopaminergic system affects many diverse processes and represents the counterpart to the vertebrate adrenergic/noradrenergic system with the classes of octopamine receptor (OAR) being homologous to those of vertebrate adrenergic receptors. However, there is still little
We have cloned two new lepidopteran octopamine transporters (OATs), members of the solute-linked carrier family 6 (SLC6) of nutrient transporters, from the CNS of the European corn borer Ostrinia nubilalis and the cabbage white Pieris rapae. Comparison of these sequences with the previously cloned
Virgin female cabbage butterflies, Pieris rapae crucivora, accept and mate with courting males, whereas mated females reject them and assume the "mate refusal posture". This study tested whether the biogenic amines, serotonin (5HT), dopamine (DA), and octopamine (OA), were responsible for this
Insecticidal Bacillus thuringiensis (Bt) delta-endotoxins are cytolytic to a range of insect cell lines in vitro. Addition of Bt var. aizawai or var. israelensis toxins to Mamestra brassicae (cabbage moth) cells in vitro increased intracellular cyclic AMP, which was paralleled by activation of
Biogenic monoamines play central roles in the nervous control of physiological processes in both vertebrates and invertebrates, each using a suite of neurotransmitters tailored through evolution. Among the ancillary proteins necessary for the deployment of monoamine transmitters are membrane-bound
The reagent 3,5-dinitrobenzoyl chloride (DNBZ-Cl) was tested for pre-column derivatization of biogenic amines (BAs). Samples were derivatized within 3 min in 1 M NaOH at ambient temperature by adding 2-propanole and 50 mM DNBZ-Cl in acetonitrile. The reaction was terminated by addition of 2 M HCl.
