Abstract

We have isolated and sequenced a Neurospora crassa ribosomal protein gene (designated crp-2) strongly homologous to the rp59 gene (CRY1) of yeast and the S14 ribosomal protein gene of mammals. The inferred sequence of the crp-2 protein is more homologous (83%) to the mammalian S14 sequence than to the yeast rp59 sequence (69%). The gene has three intervening sequences (IVSs) two of which are offset 7 bp from the position of IVSs in the mammalian genes. None correspond to the position of the IVS in the yeast gene. Crp-2 was mapped by RFLP analysis to the right arm of linkage group III. The 5' region of the gene contains three copies of a sequence, the Ribo box, previously shown to be required for transcription of both 5S and 40S rRNA genes. We speculate that the Ribo box may coordinate ribosomal protein and rRNA gene transcription.
