[Distribution of the Xvent-2 mRNA between informosomes and polysomes in early frog development]

Translational expression regulation was studied for Xvent-2 coding for a transcription factor involved in dorsoventral differentiation of amphibian embryos. The Xvent-2 mRNA was detected predominantly in informosomes at all developmental stages examined, and only its minor fraction was associated with polysomes. Expression of Xvent-2 was assumed to be regulated at the translational level, with Xvent-2 produced immediately before polypotent cells enter a certain differentiation pathway.
