Expression of Kat60Scer\UAS.cMa under the control of either Scer\GAL4elav.PU or Scer\GAL4C57 results in a significant increase in the number of satellite boutons at the neuromuscular junction in third instar larvae compared to controls (expression driven by Scer\GAL4elav.PU results in a greater increase).
Expression of Kat60Scer\UAS.cMa under the control of Scer\GAL4ppk.PG results in altered dendritic elaboration in the class IV dendritic arborization neurons: the total dendritic length, the number of dendritic termini and the total dendrite field area are significantly reduced compared to wild type.
Expression of Kat60Scer\UAS.cMa under the control of Scer\GAL4C57 results in a dramatic decrease in perinuclear microtubule density in larval muscle cells, with sparser and shorter microtubule fibres compared to wild type.

TatKO has no effect on Scer\GAL4ppk.PG>Kat60UAS.cMa-induced dendrite arbor remodeling in larval C4da neurons.
Co-expression of HDAC6Scer\UAS.cDa completely rescues the increase in satellite boutons at the neuromuscular junction seen in third instar larvae expressing Kat60Scer\UAS.cMa under the control of either Scer\GAL4elav.PU or Scer\GAL4C57.
Co-expression of HDAC6Scer\UAS.cDa does not rescue the defects in dendritic elaboration in the class IV dendritic arborization neurons which are caused by expression of Kat60Scer\UAS.cMa under the control of Scer\GAL4ppk.PG.
Co-expression of HDAC6Scer\UAS.cDa rescues the decrease in perinuclear microtubule density which is seen in larval muscle cells expressing Kat60Scer\UAS.cMa under the control of Scer\GAL4C57.
The decrease in perinuclear microtubule density which is seen in larval muscle cells expressing Kat60Scer\UAS.cMa under the control of Scer\GAL4C57 is not altered by the presence of HDAC6KO. The microtubule fibres are significantly shorter in the double mutant cells.
Kat60UAS.cMa rescues Kat6017A
The M{UAS-Kat60.M}ZH-51D insertion line effectively rescues the lethality of Kat6017A animals, even in the absence of a Scer\GAL4 driver. The anatomical and electrophysiological defects at the neuromuscular junction which are seen in Kat6017A third instar larvae are rescued by two copies of Kat60Scer\UAS.cMa.
