Expression of Xenopus Daz-like protein during gametogenesis and embryogenesis.

Author information

Division of Biological Sciences, Graduate School of Science, Hokkaido University, Sapporo, Japan.


Using a monoclonal antibody raised against Xenopus Daz-like protein (Xdazl), we showed that Xdazl is present in all stages of male and female germ cells except mature spermatozoa. Xdazl is not localized to any specific regions in early-stage embryos, in contrast to the strict localization of its mRNA in the germ plasm. Xdazl disappears after gastrulation but reappears in the primordial germ cells situated at the genital ridge. This is the first detailed report on the protein expression of a Daz-like gene during gametogenesis and embryogenesis in Xenopus, showing the difference in expression patterns of its mRNA and protein.
