| Subcellular_localization | Antibody staining revealed that CYK-4 was dramatically enriched in sperm (64 out of 64 embryos examined). Inactivation of cyk-4 by RNA interference (RNAi) indicated that staining was specific and RNAi effective. Upon fertilization, CYK-4 could be detected at the posterior cortex of the one-cell embryo of both wild-type embryos and embryos lacking maternal CYK-4. Paternal CYK-4 was observed in punctate structures, derived from sperm membranous organelles (MOs) and often associated with the sperm pronucleus. Based on nuclear morphology, paternal CYK-4 remained associated with the cortex and MOs during meiosis and the onset of polarity, a period of about 30 min. | ||
