Figure 2From: The Caenorhabditis elegansCDT-2 ubiquitin ligase is required for attenuation of EGFR signalling in vulva precursor cellsPersistent expression of egl-17::cfp in cul-4 knock out worms. (A and B) A control animal that shows the expected expression of egl-17::cfp in the primary cells after first division. (C and D) A cul-4 knock out (ko) animal in which egl-17::cfp expression is observed in the flanking secondary cells also after first division.Back to article page
