Abstract:Dis3L2 is a highly conserved 3'-5' exoribonuclease which is mutated in the human overgrowth disorders Perlman syndrome and Wilms' tumour. Here, we have generated a new dis3L2 null mutant and a UAS-nuclease-dead line in Drosophila to demonstrate that the catalytic activity of Dis3L2 is required to control proliferation in imaginal discs. Using RNA-seq on dis3L2 mutant wing discs, we show that the imaginal disc growth factor Idgf2 is responsible for driving the wing overgrowth observed in dis3L2 null mutants. ID… Show more
