概要 | Here, we show that heat shock stimulates calcineurin-dependent nuclear translocation of Prz1 and CDRE-dependent gene expression. Notably, calcineurin exhibited a dramatic change in subcellular localization, translocating from diffuse cytoplasmic to dot-like structures on heat shock. The calcineurin dots colocalized with Dcp2 or Pabp, the constituent of P-bodies or stress granules, respectively, thus suggesting that calcineurin is a component of RNA granules under heat shock. Importantly, the calcineurin inhibitor FK506 markedly inhibited the accumulation of calcineurin granules, whereas the constitutively active calcineurin strongly accumulated in the granules on heat shock, suggesting that phosphatase activity is important for calcineurin localization. Notably, the depletion of calcineurin induced a rapid appearance of Nrd1- and Pabp-positive RNA granules. The possible roles of calcineurin in response to heat shock will be discussed. |
