Fig. 1. IFD-1 and IFD-2 colocalize to juxtanuclear inclusions that become larger with age and are distinct from other organelles.
Solid white lines outline the touch neuron soma. Scale bar = 2 µm. a Ad2 touch neuron, DIC-GFP merge, strain expressing bzIs166[Pmec-4mCherry]; ifd-1(ok2404); bzSi3[Pmec-7GFP::IFD-1].
