Neuropeptide F and its expression in the yellow fever mosquito, Aedes aegypti.
Autor(es): Stanek Dawn M; Pohl Jan; Crim Joe W; Brown Mark R
Resumo: A neuropeptide F (NPF) was isolated from an extract of adult Aedes aegypti mosquitoes based on its immunoreactivity in a radioimmunoassay for Drosophila NPF. After sequencing the peptide, cDNAs encoding the NPF were identified from head and midgut. These cDNAs encode a prepropeptide containing a 36 amino acid peptide with an amidated carboxyl terminus, and its sequence shows it to be a member of the neuropeptide F/Y superfamily. Immunocytochemistry and Northern blots confirmed that both the brain and midgut of females are likely sources of NPF, found at its highest hemolymph titer before and 24 h after a blood meal.
