The primary structure of rat ribosomal protein S18.
The amino acid sequence of the rat 40S ribosomal subunit protein S18 was deduced from the sequence of nucleotides in a recombinant cDNA. S18 has 152 amino acids and has a molecular weight of 17,707. Hybridization of the cDNA to digests of nuclear DNA suggests that there are 10-13 copies of the S18 gene. The mRNA for the protein is about 600 nucleotides in length. Rat S18 is identical to mouse S18 (also referred to as KE3) and is related to Escherichia coli S13 and to other S13-like ribosomal proteins from Bacillus subtilis, from Bacillus stearothermophilus, and from plant mitochondria (Nicotiana tabacum and Zea mays).
