Figure 1. Subcellular Localization of the CUP-4 Protein. Confocal images of coelomocytes expressing either CUP-4::GFP, cytochrome
b5(C31E10.7)::GFP, or GFP::TRAM. The same GFP-expressing lines were imaged in
cup-5(
ar465) and
cup-4(
ok837) worms. Arrows indicate nucleus/ER. Arrowheads indicate the large vacuoles that accumulate in
cup-5(
ar465) coelomocytes. The outlines of the cells are drawn, when needed. Scare bar in all images, 5 um.
