Nucleotide sequence of the gene for ribosomal protein S17 from Dictyostelium discoideum.

The nucleotide sequence of the gene for the Dictyostelium homologue of eukaryotic ribosomal protein S17 has been assembled from cDNA and genomic DNA clones. The predicted primary structure of the S17 protein displays a similar level of sequence identity with its counterparts from higher eukaryotes (53%) as other Dictyostelium ribosomal proteins. Although Dictyostelium genes usually are organized in a rather simple manner, the rps17 gene harbors two introns. One of them, located immediately 3' from the ATG initiator codon, appears to be ubiquitously conserved in eukaryotic rps17 genes.
