Abstract |
The endoplasmic reticulum (ER) makes a physical contact with various intracellular organelles, such as mitochondria and lysosomes, as well as the plasma membrane (PM) via membrane contact sites. Although their cellular functions remain largely unknown, the membrane contact site between ER and the PM is thought to mediate lipid exchange between the two membranes. Here, we found that deletion of genes encoding ER-to-plasma membrane tethering proteins markedly destroyed the asymmetric distribution of Pma1p, which regulates replicative lifespan in the budding yeast Saccharomyces cerevisiae. Thus, our results suggest that ER-PM membrane contact sites regulate cell aging in yeast. Index terms - Endoplasmic reticulum, Membrane contact site, Pma1p, Aging, Saccharomyces cerevisiae. | |||||||||
