A Xenopus laevis homologue of the La autoantigen binds the pyrimidine tract of the 5' UTR of ribosomal protein mRNAs in vitro: implication of a protein factor in complex formation.

Abstract excerpt

In Xenopus and other vertebrates, ribosomal protein mRNAs share a common sequence in the 5' untranslated region (5' UTR), in particular a pyrimidine tract at the 5' end, which has been demonstrated to be involved in the translational regulation of this class of mRNAs. In previous studies, carried...
