The gating properties of Drosophila NMJ glutamate receptors and their dependence on Neto.

ABSTRACT: The Drosophila neuromuscular junction (NMJ) is a powerful genetic system that has revealed numerous conserved mechanisms for synapse development and homeostasis. The fly NMJ uses glutamate as the excitatory neurotransmitter and relies on kainate-type glutamate receptors and their auxiliary protein Neto for synapse assembly and function. However, despite decades of study, the reconstitution of NMJ glutamate receptors using heterologous systems has been achieved only recently, and there are no reports on the gating properties for the recombinant receptors. Here, using outside-out, patch clamp recordings and fast ligand application, we examine for the first time the biophysical properties of native type-A and type-B NMJ receptors in complexes with either Neto-α or Neto-β and compare them with
