Localization of GFP::UBXN-2R during the first division of the C. elegans embryo. An embryo expressing GFP::UBXN-2R (left) and mCherry::α-tubulin (right) was imaged during the first division (pronuclear migration, meeting, and centration stages). Images were acquired every 15 s with an epifluorescence microscope (AxioImager.M2; Carl Zeiss). The black arrowhead indicates the centrosomal region.
