Expressing β-Spec^GL01174 under the control of Scer\GAL4^DcG leads to third instar larval fat cells completely lacking the plasma membrane invaginations normally present in controls; peripheral lipid droplets show higher variability in size, are larger on average, and are present in lower density, as compared to controls; there are no changes in cytoplasmic medial lipid droplet size or density.

The expression of β-Spec^GL01174 under the control of Scer\GAL4^ppk.PG leads to late third instar larval class IV da neurons showing a clear loss of distal dendrites near segmental boundaries, namely significant decreases in distal dendritic branch complexity, total dendritic branch length and number of dendritic branch points, as compared to controls.
