Suppression of yeast RNA polymerase III mutations by the URP2 gene encoding a protein homologous to the mammalian ribosomal protein S20.

Abstract excerpt

URP2 was cloned as a multicopy suppressor of several temperature-sensitive mutations defective in RNA polymerase III-dependent transcription, but without effect on mutations affecting RNA polymerase I or II. This single-copy gene encodes a hydrophilic polypeptide of 121 amino acid residues with a predicted molecular mass of 13.9 kDa and a basic isoelectric point of 9.7. URP2 is a highly expressed gene, judging...
