RT organelle integrity upon hypoosmotic shock in Schizosaccharomyces pombe.";
RL FEMS Yeast Res. 14:992-994(2014).
CC -!- FUNCTION: Regulates intracellular calcium levels and cell volume for
CC survival in response to hypo-osmotic shock (PubMed:22910366). Involved
CC in maintaining vacuole integrity and protecting the nuclear envelope
CC upon hypo-osmotic shock (PubMed:25041276).
CC {ECO:0000269|PubMed:22910366, ECO:0000269|PubMed:25041276}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:22910366}; Multi-pass membrane protein
CC {ECO:0000305}. Note=Cortical endoplasmic reticulum.
CC {ECO:0000269|PubMed:22910366}.
CC -!- INDUCTION: Up-regulated by both hyper- and hypo-osmotic shocks.
CC {ECO:0000269|PubMed:22910366}.
CC -!- DOMAIN: EF-hand domain is involved in the detection of calcium
CC concentration. {ECO:0000250|UniProtKB:O74839}.
CC -!- DISRUPTION PHENOTYPE: Upon hypo-osmotic shock, cells display excessive
CC increase in cell volume compared to wild-type and undergo cell death.
CC {ECO:0000269|PubMed:22910366}.
CC -!- SIMILARITY: Belongs to the MscS (TC 1.A.23) family. {ECO:0000305}.
