αTub84BK40Q mutant third instar larvae do not display any apparent differences in the microtubule network in muscle cells compared to controls at room temperature but their microtubules (MT) are more resistant to cold-induced destabilization as the perinuclear MTs are significantly denser in αTub84BK40Q mutant muscle cells than in wild-type after cold treatment. αTub84BK40Q mutant larvae have normal number of satellite boutons at neuromuscular junctions.
αTub84BK40Q/αTub84BK40Q is a suppressor of abnormal neuroanatomy | third instar larval stage phenotype of Hsap\MAPTV337M.UAS, Scer\GAL4elav.PU
αTub84BK40Q/αTub84BK40Q is a suppressor of larval somatic muscle cell | third instar larval stage phenotype of Hsap\MAPTV337M.UAS, Scer\GAL4C57
αTub84BK40Q/αTub84BK40Q is a suppressor of cytoplasmic microtubule | third instar larval stage phenotype of Hsap\MAPTV337M.UAS, Scer\GAL4C57
αTub84BK40Q/αTub84BK40Q is a suppressor of NMJ bouton | increased number | third instar larval stage phenotype of Hsap\MAPTV337M.UAS, Scer\GAL4elav.PU
The decreased density of perinuclear microtubules (MTs) in larval muscle cells characteristic for third instar larvae expressing Hsap\MAPTV337M.Scer\UAS (with the Scer\GAL4C57 driver) as well as the excess of satellite boutons at larval neuromuscular junctions (with the Scer\GAL4elav.PU driver) is fully suppressed by αTub84BK40Q homozygosity.
