Eukaryotic ribosomes contain an acidic ribosomal protein of about 38 kDa which shows immunological cross-reactivity with the 13 kDa-type acidic ribosomal proteins that are related to L7/L12 of bacterial ribosomes. By using a cDNA clone for 38 kDa-type acidic ribosomal protein A0 from the yeast Saccharomyces cerevisiae, we have cloned a genomic DNA encoding A0 and determined the sequence of 1,614 nucleotides including about 500 nucleotides in the 5'-flanking region. The gene lacks introns and possesses two boxes homologous to upstream activation sequences (UASrpg) in the 5'-flanking region. The amino acid sequence of A0 deduced from the nucleotide sequence shows that A0 shares a highly similar carboxyl-terminal region of about 40 amino acids in length with 13 kDa-type acidic ribosomal proteins, including an identical carboxyl-terminal, DDDMGFGLFD. In the amino-terminal region A0 contains an arginine-rich segment which shows a low but distinct similarity to that of bacterial ribosomal protein L10 through which L10 is thought to bind to 23S rRNA. On the other hand, the carboxyl-terminal half of A0 is enriched with hydrophobic amino acid residues including four pairs of phenylalanine residues which are all conserved in a human homologue.
