UAS regulatory sequences drive expression of a phosphomimetic form of Lis-1, in which the two putative phosphorylation sites have been mutated to aspartic acid (T307G-C308A and A328G-G329A), tagged at the N-terminal end with Tag:HA.
Expression of Lis-1SD.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4477 does not affect the arborization of class IV dendritic arborization neurons.
