NICOTINIC ACETYLCHOLINE RECEPTOR SUBUNITS -
Nicotinic ligand-gated ion channels (nAChR) mediate the fast actions of the acetylcholine (ACh). The non-selective ion channel is formed from five subunits arranged around a central pore. The ACh binding site is formed by two adjacent α subunits. Other regulatory subunits may modulate channel pharmacology and expression. (Adapted from FBrf0183743).
Phenotypic Description from the Red Book (Lindsley and Zimm 1992)
gfA: giant fiber A (J.C. Hall; R.A. Wyman)
Adults have an aberrant startle response; they do not jump when presented with a lights-off stimulus. The dorso-longitudinal indirect flight muscles (DLMs) are abnormally driven by the giant fiber pathway neurons (see entry for ben). DLMs are driven at long and variable latencies after brain stimulation. Morphology of the giant fiber and its response to stimulation is normal. The motor neuron of the tergotrochanteral (jump) muscle is driven normally by the giant fiber. The physiological defect in gfA is probably located at the synapses between the peripherally synapsing interneuron (PSI) and the DLM motor neurons in the thoracic ganglion. gfA complements pas.

    Other Comments
    Mutations disrupt the synaptic transmission of the giant fibre (GF) - dorso-longitudinal muscle (DLM) pathway.
    gfA1/Df(1)JA27 is said to be indistinguishable from gfA1/gfA1 (Thomas and Wyman, 1984). Physiological effects of gfA1 and gfA2 are ostensibly the same.
    Adults have an aberrant startle response; they do not jump when presented with a lights-off stimulus. The dorso-longitudinal indirect flight muscles (DLMs) are abnormally driven by the giant fiber pathway neurons (see entry for ben). DLMs are driven at long and variable latencies after brain stimulation. Morphology of the giant fiber and its response to stimulation is normal. The motor neuron of the tergotrochanteral (jump) muscle is driven normally by the giant fiber. The physiological defect in gfA is probably located at the synapses between the peripherally synapsing interneuron (PSI) and the DLM motor neurons in the thoracic ganglion.
