Description:
Insects and other invertebrates use glutamate as a neurotransmitter in the central nervous system and at the neuromuscular junction. A complementary DNA from Drosophila melanogaster, designated DGluR-II, has been isolated that encodes a distant homolog of the cloned mammalian ionotropic glutamate receptor family and is expressed in somatic muscle tissue of Drosophila embryos. Electrophysiological recordings made in Xenopus oocytes that express DGluR-II revealed depolarizing responses to L-glutamate and L-aspartate but low sensitivity to quisqualate, alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA), and kainate. The DGluR-II protein may represent a distinct glutamate receptor subtype, which shares its structural design with other members of the ionotropic glutamate receptor family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schuster, C M -- Ultsch, A -- Schloss, P -- Cox, J A -- Schmitt, B -- Betz, H -- New York, N.Y. -- Science. 1991 Oct 4;254(5028):112-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zentrum fur Molekulare Biologie, Universitat Heidelberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1681587" target="_blank"〉PubMed〈/a〉
