P{UAS-fu.G13V} was generated in the course of the research described in Ascano et al. (FBrf0145120). It is identical to P{UAS-fu.Ab} except for the introduction of a mutation by site-directed mutagenesis resulting in a G13V amino acid substitution, which disrupts kinase activity. 
P{UAS-fu.G13V}11 is a second chromosome insertion.
