Abstract
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 degrees C) and heat shock (37 degrees 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.
