Abstract
Pumilio proteins regulate the translation of specific proteins required for germ cell development and morphogenesis. In the present study, we have identified the pumilio-2 in zebrafish and analyze its expression in adult tissues and early embryos. Pumilio-2 codes for the full-length Pumilio-2 protein and contains a PUF-domain. When compared to the mammalian and avian Pumilio-2 proteins, zebrafish Pumilio-2 protein was found to contain an additional sequence of 24 amino acid residues within the PUF-domain. Zebrafish pumilio-2 mRNA is expressed in the ovary, testis, liver, kidney and brain but is absent in the heart and muscle as detected by RT-PCR. The results of in situ hybridization indicate that transcripts of pumilio-2 are distributed in all blastomeres from the 1-cell stage to the sphere stage and accumulate in the head and tail during the 60%-epiboly and 3-somite stages. Transcripts were also detected in the brain and neural tube of the 24 h post-fertilization (hpf) embryos. Western blot analyses indicate that the Pumilio-2 protein is strongly expressed in the ovary, testis and brain but not in other tissues. These data suggest that pumilio-2 plays an important role in the development of the zebrafish germ cells and nervous system.
