Ribosomal protein L18 mRNA is overexpressed in human colorectal cancer
compared to normal colon tissue. We report the nucleotide sequence of
human L18 cDNA derived from a normal colon source. There were no muta
tional changes in segments of L18 cDNA derived from two tumor sources.
The L18 cDNA was 690 base pairs long and predicts a single open readi
ng frame of 564 nucleotides, encoding 188 amino acids with a M(r) = 21
621, it is homologous to rat L18 and Xenopus laevis L14.
