R361C
norpA35 homozygous adults show extremely slow deactivation kinetics.
The amplitude of quantum bumps in mutant photoreceptors is smaller than wild type (when ATP is present in the intracellular solution during recordings). When ATP is absent from the intracellular solution during recordings, the amplitude of quantum bumps from mutant photoreceptors increases to values approaching wild type.
The size and shape of the quantum bumps are unaffected, although the latency is significantly different from wild type.
The electroretinogram (ERG) of norpA35 flies shows reduced amplitude and slower response kinetics compared to that of wild-type flies.
The amplitude response to vapours of all odorants tested in the maxillary palp is not significantly different from wild type. The antennal response is also unaffected.
