Detailed Description
Statement
Reference

Expression of CaMKIIT287A.Scer\UAS under the control of Scer\GAL4VGlut-OK371 has no significant effect on bouton number/area for type Ib boutons at the larval neuromuscular junction.

Flies expressing CaMKIIT287A.Scer\UAS under the control of either Scer\GAL4ey-OK107, Scer\GAL4c305a, Scer\GAL4Mef2.247 or Scer\GAL4CaMKII.7 show normal learning (measured as 2 minute memory) in an olfactory aversive conditioning assay.

Flies expressing CaMKIIT287A.Scer\UAS under the control of either Scer\GAL4ey-OK107 or Scer\GAL4c305a show severely reduced middle-term memory (measured 3 hours after one cycle of training) in an olfactory aversive conditioning assay. This defect is still seen if expressed is limited to the adult stage using the temperature-sensitive Scer\GAL80ts.αTub84B allele.

Flies expressing CaMKIIT287A.Scer\UAS under the control of Scer\GAL4Mef2.247 show normal middle-term memory (measured 3 hours after one cycle of training) in an olfactory aversive conditioning assay.

Flies expressing CaMKIIT287A.Scer\UAS under the control of either Scer\GAL4ey-OK107 or Scer\GAL4c305a have no long-term memory (measured 24 hours after 5 cycles of spaced training) in an olfactory aversive conditioning assay.

Flies expressing CaMKIIT287A.Scer\UAS under the control of Scer\GAL4Mef2.247 show normal long-term memory (measured 24 hours after 5 cycles of spaced training) in an olfactory aversive conditioning assay.

Flies expressing CaMKIIT287A.Scer\UAS under the control of either Scer\GAL4ey-OK107 or Scer\GAL4c305a have significantly reduced anesthesia-resistant memory (measured 24 hours after 5 cycles of massed training) in an olfactory aversive conditioning assay.

Flies expressing CaMKIIT287A.Scer\UAS under the control of Scer\GAL4Mef2.247 show normal anesthesia-resistant memory (measured 24 hours after 5 cycles of massed training) in an olfactory aversive conditioning assay.

Expression of CaMKIIT287A.Scer\UAS in the motor neurons under the control of Scer\GAL4D42 does not affect bouton number.

CaMKIIT287A.Scer\UAS expression, under the regulation of Scer\GAL4109(2)80, has no effect on the total number of dendritic filopodia formed on larval class III neurons, even when two transgenes are activated. CaMKIIT287A.Scer\UAS expression does produce significantly longer filopodia (>10υm) and fewer short filopodia than in wild-type.

Males expressing CaMKIIT287A.Scer\UAS under the control of either Scer\GAL4MJ85b or Scer\GAL430Y show the same level of courtship training following 1 hour with mated females as wild-type flies.

Animals expressing CaMKIIT287A.Scer\UAS under the control of Scer\GAL4elav-C155 or Scer\GAL4Appl.G1a eclose at a normal rate and appear morphologically normal.

Third instar larvae expressing CaMKIIT287A.Scer\UAS under the control of Scer\GAL4Appl.G1a or Scer\GAL4elav-C155 do not have a significantly different roll over time than wild-type larvae.

Evoked excitatory junctional potential (EJP) amplitudes at the larval neuromuscular junction are unaffected by expression of CaMKIIT287A.Scer\UAS under the control of Scer\GAL4elav-C155. Amplitude, kinetics and frequency of spontaneous mEJPs at the larval neuromuscular junction are unaffected by expression of CaMKIIT287A.Scer\UAS under the control of Scer\GAL4Appl.G1a.

The total number of boutons at the neuromuscular junction (abdominal segment 2 on muscles 6 and 7) is not significantly altered in animals expressing CaMKIIT287D.Scer\UAS under the control of Scer\GAL4elav-C155 compared to wild type.

Expression of CaMKIIT287A.Scer\UAS under the control of Scer\GAL4unspecified at both pre- and postsynaptic sites at the larval neuromuscular junction has no significant effect.

Flies expressing CaMKIIT287A.Scer\UAS under the control of Scer\GAL4c362 show a reduction in the first reflex response compared to wild-type flies in an assay in which the resistance response from the tibial extensor motor neurons in response to flexing the femorotibial joint is measured. After the low initial response, a dramatic sensitisation of the reflex response is seen. Habituation of the response is almost absent. The axon projections of the femoral chordotonal organ sensory neurons are normal in flies expressing CaMKIIT287A.Scer\UAS under the control of Scer\GAL4c362.
