Chanklan R, et al. (2008) Inhibition of Ca2+-signal-dependent growth regulation by radicicol in budding yeast. Biosci Biotechnol Biochem 72(1):132-8
Abstract: Compelled activation of Ca(2+) signaling by exposure of zds1Delta strain Saccharomyces cerevisiae cells to external CaCl(2) leads to characteristic physiological consequences such as growth inhibition in the G(2) phase and polarized bud growth. Screening of microbial metabolites for activity alleviating the deleterious physiological effects of external CaCl(2) identified the Hsp90 inhibitor radicicol as an inhibitor of Ca(2+)-signal-dependent cell-cycle regulation in yeast. Radicicol alleviated analogous physiological effects due to the expression of a constitutively active form of calcineurin or overexpression of Swe1, the negative regulatory kinase of the Cdc28-Clb complex. Western blot analysis indicated that radicicol inhibited Ca(2+)-induced accumulation of Swe1 and Cln2.
