The endogenous AAG (lysine) codon was substituted with an AGG (arginine) codon.
Although the overall dendritic coverage in αTub84BK40R.J larval class IV da neurons appears normal, there is a progressive increase in the number of terminal branches (increase observed at 120h AEL, but not at 48h AEL), as compared to controls; dendrites show similar frequencies of both extension and retraction events, as compared to controls.
