UASp regulatory sequences drive expression of a 3kb fragment beginning 7bp upstream of the smg translation start codon and extending to the first bp after the translation stop codon (smg fragment synthesised from a cDNA template).
Expression of smgScer\UAS.P\T.cBa under the control of Scer\GAL4477 results in a reduction in the density of terminal dendritic branches of class IV da neurons in third instar larvae.
