A cDNA encodes the drosophila homolog of yeast 60S ribosomal protein YL43

We describe the nucleotide sequence of a cDNA clone isolated from Drosophila Kc cells which encodes an amino acid sequence homologous to a 60S ribosomal protein from yeast (YL43) and rat (p23). The DL43 cDNA is 320 nucleotides in length and predicts a protein of 76 amino acids and a calculated molecular mass of 8.9 kiloDaltons. Northern blot analysis demonstrates the presence of the DL43 transcript under both control (25°c) and heat shock (37°c) conditions. The Drosophila protein shares an 86% identity over the first 22 amino acids with the yeast YL43 protein and a 60% identity over the entire length of the partial sequence available for this protein.
