Statement

Flies expressing Ctet\TeTxLC[IMPTNT-V.Scer\UAS] under the control of Scer\GAL4[Trh.PB] show normal flight ability in a cylinder drop test. Air-puff stimulated flight responses of the dorsal longitudinal indirect flight muscle (DLM) of tethered flies expressing Ctet\TeTxLC[IMPTNT-V.Scer\UAS] under the control of Scer\GAL4[Trh.PB] are normal.
Males expressing Ctet\TeTxLC[IMPTNT-V.Scer\UAS] under the control of either Scer\GAL4[Or65a.4.7] or Scer\GAL4[Or65a.PF] and treated with cis-vaccenyl acetate (cVa) show an inhibition of initial courtship of mature virgin females, as do wild-type males treated with cVa.
The normal architecture of the CSD interneuron (CSDn) is only slightly altered by targeted expression of Ctet\TeTxLC[IMPTNT-V.Scer\UAS] driven by Scer\GAL4[αTub84B.PP].
Ctet\TeTxLCIMPTNT.Scer\UAS; Scer\GAL4NP1017 adults starved of water for 2 hours a normal proboscis extension response when their prothoracic legs are exposed to water.
Expression of Ctet\TeTxLCIMPTNT-V.Scer\UAS throughout the CNS, using Scer\GAL4elav-C155 as the driver, does not affect embryonic ventral cord condensation.
Expression of Ctet\TeTxLCIMPTNT-V.Scer\UAS under the control of Scer\GAL4GMR.PF does not affect 5-HT arborization in larval brains.
When Ctet\TeTxLCIMPTNT-V.Scer\UAS is driven by Scer\GAL4P2.4.Pdf no effect is seen on sensitivity to cocaine.
The olfactory attraction and repulsion behaviour of flies expressing Ctet\TeTxLC[IMPTNT-V.Scer\UAS] under the control of either Scer\GAL4[85b] or Scer\GAL4[oeC] in response to various chemicals, including butanol, benzaldehyde, propionic acid and acetone, does not significantly differ from that of wild-type.
Adults expressing Ctet\TeTxLCTNT.Scer\UAS under the control of Scer\GAL4ple.PF show a normal response in an assay in which flies are placed in a column with a conic bottom end and then suddenly tapped to the bottom to startle them.
When Ctet\TeTxLCIMPTNT-V.Scer\UAS is driven by Scer\GAL4109(2)80, mutant larvae exhibit a normal noxious heat response.
The average locomotor activity plots in light:dark (LD) cycles of flies expressing Ctet\TeTxLCIMPTNT-V.Scer\UAS under the control of Scer\GAL4per.PK or Scer\GAL4tim.PE is indistinguishable from those of control flies. Expression of Ctet\TeTxLCIMPTNT-V.Scer\UAS under the control of Scer\GAL4per.PK under constant darkness conditions does not result in a decrease in rhythmicity of locomotor behaviour. Expression of Ctet\TeTxLCIMPTNT-V.Scer\UAS under the control of Scer\GAL4tim.PE under constant darkness conditions results in a decrease in in the number of rhythmic flies in a locomotor activity assay.
When expression is driven by Scer\GAL4c17 in the giant fibre the response in the TTM to repetitive firing is wild type.
When Ctet\TeTxLCIMPTNT-V.Scer\UAS is driven by Scer\GAL4eve.RRC in aCC neurons, excitatory post-synaptic currents (epscs) are present in 14/18 neurons. Sustained inward currents are also seen in 14/18 neurons.
Flies expressing Ctet\TeTxLCIMPTNT-V.Scer\UAS under the control of Scer\GAL4MZ1369 have no obvious developmental defects. The wild-type columnar organisation of the medulla is recognisable in the optic lobes and the arborisations of the Fas2-positive lamina monopolar cells in the distal medulla are normal.
Scer\GAL4 mediated expression has no effect on viability.

per[01] mutant files co-expressing per[Scer\UAS.cBa] and Ctet\TeTxLC[TNT.Scer\UAS] under the control of Scer\GAL4[Mai179] display morning anticipation in their locomotor activity, but they completely lose evening anticipation, compared with controls with Ctet\TeTxLC[IMPTNT-V.Scer\UAS] expression.
