title: Translational control mediated by UA-rich sequences.
abstract: Several messenger RNAs coding for cytokines, growth factors or oncoproteins contain a conserved UA-rich sequence in their 3' untranslated regions. This sequence, which is composed of several interspersed repeats of the octanucleotide UUAUUUAU, is a key element in the posttranscriptional regulation of these mRNAs. Previously shown to be involved in mRNA destabilization, these UA-rich elements can also strongly influence mRNA translation. A translation inhibition mediated by these sequences has indeed been observed in vitro as well as in frog oocyte or in somatic cells.
