Primary hemocytes from larvae expressing ChcGD14095 under the control of Scer\GAL4srp.PU show strongly reduced internalization of sSpi-GFP protein (spi encodes the principal ligand of the EGFR pathway) at low sSpi-GFP conditions (treatment with 4 ng/ml of sSpi-GFP) but not at high sSpi-GFP conditions (treatment with 30 ng/ml of sSpi-GFP), as compared to controls.

Third larval instar adipocytes expressing ChcGD14095 under the control of Scer\GAL4SPARC-MI00329-GAL4 show a significant increase in both plasma membrane depth and sinuosity compared to control cells.

Expression of ChcGD14095 under the control of Scer\GAL4AB1 results in a complete block in glue granule formation in most larval salivary gland cells, with only rare cells exhibiting small granules. Pupal cases are poorly adherent.

Expression of ChcGD14095 under the control of Scer\GAL4Appl.G1a disrupts synaptic vesicle endocytosis. Synaptic vesicle size is increased in these flies with respect to wild-type. Boutons exhibit large cisternae-like membrane structure rarely seen in wild-type. The number of docked synaptic vesicles at ChcGD14095 synapses is increased with respect to wild-type, indicating that synaptic vesicles are present at release sites but unable to fuse efficiently with the plasma membrane.

Synapses expressing ChcGD14095 under the control of Scer\GAL4Appl.G1a display an activity dependent reduction in excitatory post-synaptic current amplitude.

Flies expressing ChcGD14095 under the control of Scer\GAL4Appl.G1a produce an activity-dependent reduction in excitatory post-synaptic current (EPSC) amplitude with rapid onset during train stimulation. Vesicle size is increased in these mutants.

Adults expressing ChcGD14095 under the control of the cardioblast-specific Scer\GAL4tin.CΔ4 driver show significantly reduced survival on day 6 after a shift to 29[o]C compared to control flies.

Adults expressing ChcGD14095 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.

Expression under the control of Scer\GAL4Mef2.PR results in early pupal lethality.

Expression under the control of Scer\GAL4pnr-MD237 results in lethality before the pupal stage.
