Small ribosomal subunit protein eS25
ribosome
Cloning and sequencing a cDNA encoding human ribosomal protein S25.
A full-length cDNA clone has been isolated from a cDNA library prepared from mRNA of adriamycin-resistant human leukemia HL60 cells. The nucleotide sequence of this cDNA has been determined and the protein coded for by the gene identified. The cDNA encodes a polypeptide of 125 amino acids (aa) with a deduced Mr of 13750. The deduced aa sequence of this protein has 56% homology to yeast ribosomal protein S31. Western-blot analysis using antibodies directed against a synthetic peptide based on the deduced aa sequence identifies the gene product as the human ribosomal protein S25.
