Research Abstract

In zebrafish, primordial germ cells (PGCs) are determined by a specialized maternal cytoplasm, germ plasm, which forms at the distal ends of the cleavage furrows in 4-cell embryos. During embryogenesis, miR-430 represses some germ plasm mRNAs incorporated into somatic cells. Here we showed that a germline-specific RNA-binding protein DAZL counteracts the miRNA-mediated repression of tdrd7 and dazl mRNAs. Also we showed that, in zebrafish embryos, miRNA inhibits translation of the target mRNA in a deadenylationand PABP-independent manner at early time points.
