A. Subcellular distribution of GEX-3::GFP at apical and basal regions of the intestine. GEX-3::GFP localization relative to apical terminal web (a-IFB-2), an apical membrane-bound protein (a-ERM-1), and the basal plasma membrane protein LET-413/Scribble. The solid white squares mark the regions enlarged on the right.
B. Subcellular distribution of GEX-3::GFP relative to regulators of CME. Relative distribution of GFP::CHC-1, APA-2, GFP::RAB-5, GEX-3::GFP and PH::GFP. The arrows indicate the basal membrane at the junction between two intestinal cells.
C. Effect of GEX-3 on GFP::hTfR localization. The localization of GFP::hTfR is compared to that of APA-2 and RAB-5 in wild type animals and in animals depleted of GEX-3 via RNAi. White arrows indicate regions of overlap. The graphs document the number of puncta expressing both markers within a given rectangular region.
