The following constructs are unpublished: UAS-Dlg5: CG6509 (Dlg5) under UAS control UAS-Dlg5-GFP: GFP-tagged CG6509 (Dlg5) under UAS control UAS-Dlg5-RNAi: CG6509 (Dlg5) RNAi under UAS control UAS-cycEI-DeltaPEST - cycE type I with 3' PEST sequences deleted UAS-cycEI-Delta40 - cycE type I with the first 40 amino acids deleted UAS-cycEI-genomic - genomic minigene of cycE type I (made by Christian Lehner) UAS-cycEII - cycE type II (the hs-cycEII construct (FBtp0015493) published in FBrf0141482 was used to make this UAS-cycEII construct) UAS-sina-myc - full-length sina tagged with myc, made by Ross Dickins and David Bowtell UAS-sina-DeltaRING-myc - myc-tagged sina deleted for the RING domain(presumed dominant-negative)
