Abstract: Crumbs is a transmembrane protein and apical determinant in Drosophila epithelial cells. Its cytoplasmic tail contains a PDZ and a FERM domain-binding site through which Crumbs interacts with the FERM proteins Yurt, Moesin and Expanded. Recent evidence suggests that Crumbs can also interact with the uncharacterised FERM proteins CG34347 and Cdep. The main objective of my thesis was to generate mutations in CG34347 and Cdep to facilitate the functional analysis of these genes. I generated a mutation for Cdep that remains to be characterised and two mutant lines for CG34347; one lacking the first exon and one lacking the entire gene, using a FRT-based recombination strategy. Both CG34347 mutants cause severe ovarian defects. The most consistent defect is a multilayering of the interfollicular stalk. These defects are also observed when Notch, Hippo, Wingless and Hedgehog signalling pathways are overactive in ovaries suggesting that CG34347 participates in one of those pathways.
