Expressing MedJF02218 under the control of Scer\GAL4ppk.PU results in a significantly reduced number of branch points in the dendrites of class IV dendritic arborizing neurons in third instar larvae compared to wild-type controls.
Expression of MedJF02218 under the control of Scer\GAL4A9 results in the loss of distal parts of the L3, L4 and L5 wing veins and a decrease in wing size.
The adulthood-only expression of MedJF02218 under the control of Scer\GAL4esg.PU (in combination with Gal80[ts], for temporal regulation of expression) leads to a significant decrease in the relative and absolute size of secondary cell nuclei compared to neighboring main cells and wild-type controls; this expression does not affect the size of main cell nuclei compared to controls. The adulthood-only expression under the control of Scer\GAL4dsx.KI (and Gal80[ts]) leads to a significant decrease in the number of secretory vesicles within accessory gland secondary cells, associated with a significant decrease in the size of the largest multivesicular body/lysosome, as compared to controls; there is also a severe decrease in the secretion of (CD63-positive) exosomes into the accessory gland lumen.
The adulthood-only expression of MedJF02218 under the combined control of Scer\GAL4spi-NP0261 and Gal80[ts] also results in both virgin and mated males showing a significant increase in the number of dense core granule compartments within accessory gland secondary cells, as compared to matched controls.
