Molecular cloning of the RPS0 gene from Candida tropicalis.

2001

The Saccharomyces cerevisiae RPS0 A and B genes encode proteins essential for maturation of the 40S ribosomal subunit precursors. We have isolated a homologue of the RPS0 gene from Candida tropicalis, which we named CtRPS0. The C. tropicalisRPS0 encodes a protein of 261 amino acid residues with a predicted molecular weight of 28.65 kDa and an isoelectric point of 4.79. CtRps0p displays significant amino acid sequence homology with Rps0p from C. albicans, S. cerevisiae, Neurospora crassa, Schizosaccharomyces pombe, Pneumocystis carinii and higher organisms, such as human, mouse and rat. CtRPS0 on a high copy number vector can complement the lethal phenotype linked to the disruption of both R…
