Characterization of SIS1, a Saccharomyces cerevisiae homologue of bacterial dnaJ proteins.

Abstract excerpt

The Saccharomyces cerevisiae SIS1 gene was identified as a high copy number suppressor of the slow growth phenotype of strains containing mutations in the SIT4 gene, which encodes a predicted serine/threonine protein phosphatase. The SIS1 protein is similar to bacterial dnaJ proteins in the amino-terminal third and carboxyl-terminal third of the proteins. In contrast, the middle third of SIS1 is not similar to...
