Drosophila ribosomal protein L18a: cDNA sequence, expression and chromosomal localization of the gene.
We describe the cDNA sequence of the Drosophila homologue of the rat ribosomal protein L18a. The protein sequence predicted has identical or conservatively substituted amino acids in 80% of positions. It is distinctly basic in character with an overall net positive charge of + 20. Analysis of L18a RNA with the Northern blot technique shows it to be expressed both during embryonic development and in the adult fly. In situ hybridisation to polytene chromosomes reveals that the L18a gene(s) is located at 54B on the second chromosome.
