The expression of RNAi constructs directed against six additional genes caused a Egfr-like phenotype: couch potato (cpo), which encodes for an RNA binding protein, CG13653, a gene with unknown function, furry (fry), which encodes for an actin cytoskeleton regulator, echinoid (ed), which encodes for a homophilic cell adhesion molecule, Eb1, which encodes for a microtubule-associated protein, and WASp (Wsp) the fly homolog of the Wiskott-Aldrich Syndrome family of actin nucleation factors (Figure 3B-G). Here, EGFR is linked to Wiskott-Aldrich syndrome.
