Cadherin-based adherens junctions (AJs) mediate cell adhesion and regulate cell shape change. The nectin-afadin complex also localizes to AJs and links to the cytoskeleton. Mammalian afadin has been suggested to be essential for adhesion and polarity establishment, but its mechanism of action is unclear. In contrast, Drosophila melanogaster's afadin(More)
The ability to edit the genome is essential for many state-of-the-art experimental paradigms. Since DNA breaks stimulate repair, they can be exploited to target site-specific integration. The clustered, regularly interspaced, short palindromic repeats (CRISPR)/cas9 system from Streptococcus pyogenes has been harnessed into an efficient and programmable(More)
The spatio-temporal regulation of gene expression lies at the heart of animal development. In this article we present an overview of our recent work to apply systems biological approaches to the study of transcription and microRNA-mediated translation control in Drosophila development. We have identified many new cis-regulatory elements within the(More)
Traditional loss-of-function studies in Drosophila suffer from a number of shortcomings, including off-target effects in the case of RNA interference (RNAi) or the stochastic nature of mosaic clonal analysis. Here, we describe minimal in vivo GFP interference (miGFPi) as a versatile strategy to characterize gene function and to conduct highly stringent,(More)
