Sequence analysis of the newly defined SSU81 gene revealed an adjacent open reading frame (ORF) encoding a protein whose deduced amino acid sequence is identical to that of ribosomal protein L17. The DNA sequence of this region is different from that of the RPL17A gene and therefore represents a duplicate gene encoding L17. We have designated this gene RPL17B . The RPL17B coding region is split by an intron that occurs in the same position (codons 14/15) as the intron in RPL17A . The RPL17B promoter region includes two TATA boxes, a canonical UAS RPG motif, and several pyrimidine‐rich tracts. RPL17B was mapped by CHEF and lambda clone grid hybridization blots to the right arm of chromosome V, linked to the TRP2 and RAD51 genes. A partial ORF was identified adjacent to RPL17B and SSU81 that is homologous to an ORF (designated A509) physically linked to RPL17A . This observation, and the identical position of the introns within the RPL17 genes, suggest that one RPL17 locus arose by duplication and translocation of the other. The complete 3·8 kbp DNA sequence encompassing RPL17B has been entered in the GenBank data library under Accession Number U15653.
