| Subcellular Localization | EGG-4/5 localize to the cortex of oocytes. In addition, EGG-4/5 were also detected in oocyte nuclei. The cortical and nuclear signals were eliminated by RNAi codepletion of EGG-4 and EGG-5, confirming that they correspond to endogenous EGG-4/5. Staining of hermaphrodites homozygous for single deletions in either EGG-4 or EGG-5 gave the same pattern as wild-type, confirming that EGG-4 and EGG-5 are both expressed in oocytes. In zygotes in meiosis II, EGG-4/5 were enriched on subcortical puncta, also positive for EGG-3. EGG-3-positive puncta invade the cytoplasm during meiosis II. EGG-4/5 puncta, in contrast, were prominent only near the cortex and around the sperm pronucleus. No EGG-4/5 were detected above background in 2-cell embryos. |
