Molecular biology of insect neuronal GABA receptors

Web6.3. Detection of Resistance to Dieldrin (Rdl) In many insect species, resistance to cyclodiene insecticides is caused by amino acid substitutions at a single residue within the M2 transmembrane region of the γ-aminobutyric acid (GABA) receptor subunit termed Rdl (resistance to dieldrin) . These mutations have also been shown to confer low ... WebSep 25, 2013 · One or more mechanisms may be involved in physiological resistance, including alteration of target site nerve receptors (e.g., kdr, Rdl and Ace. 1R) and detoxification via increased enzyme activity of non-specific esterases, glutathione S -transferases and P-450 mediated monooxygenases (mixed function oxidases) [ 20 ]. gwen stefani eye makeup tutorial https://bodybeautyspa.org

WebJan 18, 2014 · The resistance to dieldrin (RDL) receptor is an insect pentameric ligand-gated ion channel (pLGIC). It is activated by the neurotransmitter γ-aminobutyric acid (GABA) binding to its extracellular domain; hence elucidating the atomistic details of this interaction is important for understanding how the RDL receptor functions.
