UAS regulatory sequences drive expression of a DsRed(Unk) fluorescent protein. A genomic fragment containing the mir-124 pre-miRNA hairpin has been inserted into the DsRed(Unk) 3'UTR.
Expression of mir-124Scer\UAS.T:Disc\RFP under the control of Scer\GAL4221 results in a decrease in the average number of dendritic branches in the ddaD and ddaE neurons of larvae.
