UASp sequences regulate expression of a full-length l(2)gd1 cDNA (from the LD23056 clone), in which all the consensus Cdk1 phosphorylation sites have been mutated to a phosphomimetic Glu residue (amino acid substitutions S217E, T222E, S225E, T239E, T242E, S254E, T347E, T436E, S442E, S445E, T457E, T465E, S474E and T712E). The coding sequence is tagged at the N-terminal end with EGFP.
