Cytology
Description

UASp regulatory sequences control expression of a 3.6kb genomic fragment that contains the Lkb1 transcription unit, mutated to contain a modification (S535E) that is intended to mimic phosphorylation at a putative PKA phosphorylation site. A GFP tag has been inserted at the N-terminal end of the Lkb1 open reading frame.

      Expression of the lkb1S535E.Scer\UAS.P\T.T:Avic\GFP transgene fails to rescue the oocyte polarity and nurse cell fusion phenotypes of Pka-C1H2 germline clones.

      Comments

      Scer\GAL4mat.αTub67C.T:Hsim\VP16; lkb1S535E.Scer\UAS.P\T.T:Avic\GFP rescues loss of polarity in lkb14A4-2 germ line clone oocytes. lkb1S535E.Scer\UAS.P\T.T:Avic\GFP; Scer\GAL4arm.PS rescues the lethality due to lkb14A4-2/lkb14B1-11. The ovaries of the resulting flies have normal follicle cell organisation and normal polarity in approximately 80% of their oocytes.
