GFP protein-trap insertions. A) Mapping insertions to gene features: the 1,522 insertions reported in the FlyTrap database were mapped to Release 5.3 of the D. melanogaster gene annotation, with the results relative to gene features shown. B) Overlap in protein trap targets: the 226 protein trap targets with matching frame information reported in FlyTrap originate from three large-scale screens and there is considerable overlap between the gene sets obtained.
