title: Nucleotide sequence and 40 S subunit assembly of Xenopus laevis ribosomal protein S22.
abstract: We have isolated and determined the nucleotide sequence of a cDNA encoding Xenopus laevis ribosomal protein S22. A synthetic S22 mRNA derived from this cDNA directs the synthesis of an in vitro translation product that is indistinguishable from S22 purified from Xenopus ovarian ribosomes. In vitro translated S22 is assembled into 40 S subunits when microinjected into the cytoplasm of oocytes. Analysis of the derived amino acid sequence indicates that Xenopus S22 is homologous to Escherichia coli ribosomal protein S10.
