Figure 6. Localization of GFP-Tagged Dynein Suppressor Proteins in Wild-Type Embryos Insets show 2x magnification of meiotic spindles. (A-D) DYLT-1: oocyte nuclear envelopes (A), meiotic spindle poles (B), nuclear envelopes prior to mitosis (C), and centrosomes and mitotic spindle poles (D). Mitotic localization is most robust in embryos beyond the 12-cell stage; weaker localization to spindle poles was detectable in one- and two-cell stage embryos (see Figure 7). (E-H) DYRB-1: similar to DYLT-1, except weaker subsequent to meiosis. (I-L) K04F10.3: endoplasmic reticulum-like; meiotic spindle poles (I) and pericentrosomal during mitosis (I-L). (M-P) NPP-22: nuclear envelope and pericentrosomal (also endoplasmic reticulum-like, except for absence of meiotic spindle localization). (Q-T) EFA-6.c: nonpolarized cell cortex in oocytes and early one-cell zygotes (Q-R), anterior cell cortex in one-cell embryos subsequent to pseudocleavage (S) and present at the interface of the AB and P1 cells (T), undetectable by the four-cell stage (unpublished data). (U-X) MOP-25.2: midbody after cytokinesis (arrows indicate the spot of localization) and weak localization to spindle poles (unpublished data). (Y-B') F10E7.8: pronuclear and nuclear (cytoplasmic signal is at least partially due to endogenous autofluorescence in this weakly expressing line). (C'-F') STAR-2 (a nonspecific suppressor gene): apparent localization to germline P-granules.
