The characterization of the yeast SKN7 gene and the identification of a maize carboxypeptidase homologue
"The Saccharomyces cerevisiae SKN7 gene has been identified through a search for genes which, at a high copy number, could restore the growth of the $kre9 Delta$ disrupted strain showing a cell wall $ beta$-glucan defect. SKN7 was mapped to the right arm of chromosome VIII, and is predicted to encode a 70 kDa protein, Skn7p, with a region of homology to the DNA binding domain of the yeast heat shock transcription factor, Hsf1p. Skn7p also has a domain which shows similarity to the prokaryotic receiver modules found on an extensive family of two-component response regulators, including the product of the rcsC gene. While restoring the growth rate to near wild type levels, SKN7 does not appear to restore the $ beta$-glucan levels of the $kre9 Delta$ mutant. However, SKN7-suppressed cells show a partially restored cellular morphology, and a restored cell wall resistance to mechanical stress. SKN7 does not suppress other mutations in the ($1 rightarrow6$)-$ beta$-glucan biosynthetic pathway, suggesting that it does not act as a general bypass suppressor of this glucan." --
