Detailed Description

The expression of Hsap\UBE3AScer\UAS.cRa under the control of Scer\GAL4repo leads to adults showing progressive bang-induced paralysis and heat-induced paralysis, but not photogenic paralysis. This expression also leads significant decreases in the amplitudes of On transients, Off transients and photoreceptor potential in electroretinograms, as compared to controls.

The expression of Hsap\UBE3AScer\UAS.cRa under the control of either Scer\GAL4ap.PU or Scer\GAL4GMR.PU does not lead to obvious wing or eye defect, as compared to controls.

Expression of Hsap\UBE3AScer\UAS.cRa in a subset of DA sensory neurons using Scer\GAL4221 causes decreased dendritic branching of ddaE and ddaF neurons.

Expression of Hsap\UBE3AScer\UAS.cRa under the control of Scer\GAL4GMR.PF at 25[o]C has no discernable effect on eye development.

The co-expression of Hsap\UBE3AUAS.cRa and HPV18\E6UAS.Tag:MYC under the control of Scer\GAL4ap.PU in a Magibst-homozygous background leads to pupal lethality.

The co-expression at room temperature of Hsap\UBE3AUAS.cRa and HPV18\E6UAS.Tag:MYC under the control of Scer\GAL4ap.PU leads to fully penetrant adult wing defects, including smaller and blistered held-out wings that are full of melanized tissue, while co-expression at 29[o]C leads to increased apoptosis in the dorsal compartment of third instar larval wing discs (assessed by the number of Casp3-positive cells), as compared to controls; the severity of wing defects is ameliorated by additional co-expression of MagiUAS.mCherry or MagiΔWW.UAS.Tag:FLAG, but not of MagiΔPDZ.UAS.Tag:FLAG, scribUASp.GFP or dlg1UAS.EGFP, while the third instar larval wing disc defects are rescued by the additional co-expression of MagiUAS.mCherry but not of scribUASp.GFP or bskDN.UAS; additional co-expression of BacA\p35UAS.cHa also rescues the increased apoptosis at the dorsal compartment of third instar larval wing discs without leading to disc overgrowth, but induces basal delamination of cell clusters, as compared to controls.

The triple co-expression of Hsap\UBE3AUAS.cRa, HPV18\E6UAS.Tag:MYC and Ras85DV12.cUa.UAS under the control of Scer\GAL4ap.PU from the first or second instar larval stage onwards (by the use of Gal80[ts]) results in the most highly expressing cells within the dorsal compartment of the third instar larval imaginal disc adopting a fibroblast-like and flat morphology, displaying filopodial-like processes and delaminating at the basal side of the columnar epithelium, although without crossing the dorsal-ventral boundary, as compared to controls.

The co-expression of Hsap\UBE3AUAS.cRa and HPV18\E6UAS.Tag:MYC under the control of Scer\GAL4GMR.PU leads to a fully penetrant rough eye phenotype, disorganized and fused ommatidia (resulting in increased numbers of cone cells, bristle cells and primary, secondary and tertiary pigment cells per ommatidium), and abnormal adherens junctions between photoreceptors, as compared to the single expressions or wild-type controls; this rough eye phenotype is enhanced by the co-expression of either InRUAS.cUa, leading to overgrowth and out-pocketing of the eye tissue, or InRDN.UAS.cUa, leading to severe eye necrosis, but is not modified by heterozygosity for Akt104226, hhAC, witA12, Tak12527, BuffyH37, DebclE26, hop2 or Stat92E06346, or by the additional co-expression of rlSem.cUa.UAS, armS10.UAS.Tag:MYC, ykiUAS.EGFP,Tag:HA, bskDN.UAS, DebclUAS.cUa or p53H159N.UAS.Ex.

The triple co-expression of Hsap\UBE3AUAS.cRa, HPV18\E6UAS.Tag:MYC and either Ras85DV12.cUa.UAS or Nint.U.UAS under the control of Scer\GAL4GMR.PU leads to the migration of a considerable proportion of expressing eye tissue cells into distant pupal tissues (e.g. abdomen), as compared to controls; the Nint.U.UAS triple co-expression condition also leads to pharate lethality, while the Ras85DV12.cUa.UAS triple co-expression condition does not suppress the pupal lethality induced by the single expression of Ras85DV12.cUa.UAS. The triple co-expression of Hsap\UBE3AUAS.cRa and the different HPV18\E6V158A.UAS.Tag:MYC allele with Ras85DV12.cUa.UAS, but not Nint.U.UAS, under the control of Scer\GAL4GMR.PU leads to the migration of a considerable proportion of the expressing eye cells into distant pupal tissues (e.g. abdomen), as compared to controls.

Co-expression of Hsap\UBE3AScer\UAS.cRa and pblEP3415 under the control of Scer\GAL4GMR.PF at 25[o]C rescues much of the effect of pblEP3415 overexpression. Although eyes still have a mild rough appearance, fewer than 3% exhibit necrotic foci and the ommatidia are much better organised and well formed than in pblEP3415 (Scer\GAL4GMR.PF) flies, including six to seven photoreceptor cells per ommatidium.

The synergistic effect of pblEP3415 and fafEP381 can be overcome by co-expression with Hsap\UBE3AScer\UAS.cRa (all under the control of Scer\GAL4GMR.PF.
