•   hos2 mutants of the fission yeast Schizosaccharomyces pombe showed the phenotype of high osmolarity sensitivity for growth. An S. pombe strain carrying the hos2-M10 allele cannot form colonies on agar plates containing 2 M glucose, but the parental strain can do so very well, as demonstrated previously. In this study, the hos2+ gene was identified as one that encodes a small protein of 94 amino acids, which shows no sequence similarity to any other proteins in the current databases. The hos2-M10 mutation resulted in Gln-62 to TAG-termination codon. A Hos2-defective (hos2Δ) strain, which we then constructed, showed the phenotype of high osmolarity sensitivity, as in the case of the original hos2-M10 mutant. For this hos2Δ mutant, three multicopy suppressor genes were isolated and one of which was identified as the pgk1+ gene, encoding a phosphoglycerate kinase.
