Rdl insect
WebA cloned Drosophila gamma-aminobutyric acid GABA receptor subunit ( Rdl) has been stably expressed as a functional homo-oligomeric ion channel in a Drosophila cell line [14]. Rdl is expressed in both the embryonic central and peripheral nervous system [15]. WebJan 5, 2024 · The RDL receptor is one of the most relevant protein targets for insecticide molecules. It belongs to the pentameric ligand-gated ion channel (pLGIC) family. Given that the experimental structures of pLGICs are difficult to obtain, homology modeling has been extensively used for these proteins, particularly for the RDL receptor. However, no detailed …

WebKnowing that Rdl can coassemble with LCCH3 (a Drosophila GABA receptor-like subunit showing sequence similarity to vertebrate beta subunit GABAA receptors) in baculovirus infected insect cells, we compared the localization of these two receptor subunits in order to identify any potential overlap in their spatial or temporal distribution. WebBACKGROUND Fluralaner, a novel pesticide that targets the γ‐aminobutyric acid (GABA) receptor (GABAR) subunit of resistant to dieldrin (RDL), exhibits strong potential to be an insecticide to control agricultural insect pests. However, the risk and action of fluralaner to economic insects, e.g., honeybee Apis mellifera Linnaeus, remains unclear.
