Drosophila tachykinin receptor, a neurokinin receptor cloned from the fruit fly Drosophila melanogaster , is a G‐protein‐coupled receptor, which upon activation by a peptide agonist induces a transient increase in the concentration of intracellular calcium. The functional assay based on aequorin‐derived luminescence triggered by receptor‐mediated changes in Ca 2+ levels was used to examine and compare the effect of tachykinin‐related peptides from different species. Among the endogenous Drosophila peptides, Drm ‐TK I induced the strongest calcium response. The most potent tachykinin‐related peptides from Leucophaea maderae , Locusta migratoria , and Calliphora vomitoria , were partial agonists at the Drosophila tachykinin receptor.
