Characterization of a new member of the sea urchin Paracentrotus lividus hsp70 gene family and its expression

1992

We have sequenced a second gene of the hsp70 family derived from a genomic clone of the sea urchin, Paracentrotus lividus. The structure of this gene, named hsp70IV gene, is interrupted by one intron and differs from the previously analyzed sea urchin hsp70II gene, which contains several introns. Two open reading frames of hsp70IV gene encode a predicted protein of 639 amino acids with an M(r) of 69,672. The 5' flanking region of the gene contains a putative TATA element, three heat-shock elements made up of some arrays of the 5-bp units, NGAAN and NTTCN (N = A,C,G or T), a canonic consensus sequence for binding of the regulatory activating transcription factor (ATF), and a purine box. The …

Myo-inositol counteracts the vegetalizing effect of lithium on P.lividus embryos

1992

Abstract The vegetalizing effect of LiCl on sea urchins embryos can be counteracted by the addition of myo-inositol. This observation is discussed in connection with similar results recently reported for amphibian embryos.
