Amiodarone 40-50 Ysp2p Saccharomyces cerevisiae S288C 0-4 16962064-3 2006 We have described a novel mitochondrial protein, Ysp2, acting in the amiodarone-induced death cascade. Amiodarone 69-79 Ysp2p Saccharomyces cerevisiae S288C 49-53 16962064-4 2006 After amiodarone addition both the control and amiodarone-resistant ysp2-deleted cells formed ROS, but the mutant (unlike the control) did not undergo the mitochondrial thread-to-grain transition. Amiodarone 6-16 Ysp2p Saccharomyces cerevisiae S288C 68-72 16962064-4 2006 After amiodarone addition both the control and amiodarone-resistant ysp2-deleted cells formed ROS, but the mutant (unlike the control) did not undergo the mitochondrial thread-to-grain transition. Amiodarone 47-57 Ysp2p Saccharomyces cerevisiae S288C 68-72 16962064-4 2006 After amiodarone addition both the control and amiodarone-resistant ysp2-deleted cells formed ROS, but the mutant (unlike the control) did not undergo the mitochondrial thread-to-grain transition. Reactive Oxygen Species 94-97 Ysp2p Saccharomyces cerevisiae S288C 68-72 16962064-5 2006 To test whether the action of Ysp2 is amiodarone-specific we tried to induce PCD by other agents. Amiodarone 38-48 Ysp2p Saccharomyces cerevisiae S288C 30-34 16962064-6 2006 We have found that acetic acid-induced PCD also depends on Ysp2. Acetic Acid 19-30 Ysp2p Saccharomyces cerevisiae S288C 59-63 16962064-8 2006 We suggest that intracellular acidification results in the protonation of superoxide anion (O2-*) to form HO2, one of the most aggressive ROS, which in turn induces Ysp2-mediated PCD. Superoxides 74-90 Ysp2p Saccharomyces cerevisiae S288C 165-169 16962064-8 2006 We suggest that intracellular acidification results in the protonation of superoxide anion (O2-*) to form HO2, one of the most aggressive ROS, which in turn induces Ysp2-mediated PCD. Superoxides 92-94 Ysp2p Saccharomyces cerevisiae S288C 165-169 16962064-8 2006 We suggest that intracellular acidification results in the protonation of superoxide anion (O2-*) to form HO2, one of the most aggressive ROS, which in turn induces Ysp2-mediated PCD. perhydroxyl radical 106-109 Ysp2p Saccharomyces cerevisiae S288C 165-169 16962064-8 2006 We suggest that intracellular acidification results in the protonation of superoxide anion (O2-*) to form HO2, one of the most aggressive ROS, which in turn induces Ysp2-mediated PCD. Reactive Oxygen Species 138-141 Ysp2p Saccharomyces cerevisiae S288C 165-169 33255682-4 2020 At ER-PM CSs, Lam2 and Lam4 associate with Laf1/Ymr102c and Dgr2/Ykl121w (paralogous WD40 repeat-containing proteins) that reportedly bind sterol. Sterols 139-145 Ysp2p Saccharomyces cerevisiae S288C 14-18 33255682-2 2020 Two of the six family members-Lam2/Ltc4 (initially Ysp2) and paralog Lam4/Ltc3-localize to ER-plasma membrane (PM) contact sites (CSs) and mediate retrograde ergosterol transport from the PM to the ER. Ergosterol 158-168 Ysp2p Saccharomyces cerevisiae S288C 30-34 33255682-2 2020 Two of the six family members-Lam2/Ltc4 (initially Ysp2) and paralog Lam4/Ltc3-localize to ER-plasma membrane (PM) contact sites (CSs) and mediate retrograde ergosterol transport from the PM to the ER. Ergosterol 158-168 Ysp2p Saccharomyces cerevisiae S288C 35-39 33255682-2 2020 Two of the six family members-Lam2/Ltc4 (initially Ysp2) and paralog Lam4/Ltc3-localize to ER-plasma membrane (PM) contact sites (CSs) and mediate retrograde ergosterol transport from the PM to the ER. Ergosterol 158-168 Ysp2p Saccharomyces cerevisiae S288C 51-55 33255682-3 2020 Our prior work demonstrated that Lam2 and Lam4 are substrates of TORC2-regulated protein kinase Ypk1, that Ypk1-mediated phosphorylation inhibits their function in retrograde sterol transport, and that PM sterol retention bolsters cell survival under stressful conditions. Sterols 175-181 Ysp2p Saccharomyces cerevisiae S288C 33-37 33255682-8 2020 Lam2 phosphorylated by Ypk1, and Lam2 with phosphomimetic (Glu) replacements at its Ypk1 sites, exhibited a marked reduction in Laf1 binding. Glutamic Acid 59-62 Ysp2p Saccharomyces cerevisiae S288C 33-37 33255682-9 2020 Thus, phosphorylation prevents Lam2 interaction with Laf1 at ER-PM CSs, providing a mechanism by which Ypk1 action inhibits retrograde sterol transport. Sterols 135-141 Ysp2p Saccharomyces cerevisiae S288C 31-35 32047490-6 2020 Surprisingly, the quadruple deletant and LAM2/LAM4 double deletion strain showed increased tolerance to the azole antifungals clotrimazole and miconazole. Azoles 108-113 Ysp2p Saccharomyces cerevisiae S288C 41-45 32047490-6 2020 Surprisingly, the quadruple deletant and LAM2/LAM4 double deletion strain showed increased tolerance to the azole antifungals clotrimazole and miconazole. Clotrimazole 126-138 Ysp2p Saccharomyces cerevisiae S288C 41-45 32047490-6 2020 Surprisingly, the quadruple deletant and LAM2/LAM4 double deletion strain showed increased tolerance to the azole antifungals clotrimazole and miconazole. Miconazole 143-153 Ysp2p Saccharomyces cerevisiae S288C 41-45 26001273-3 2015 StART-like domains from Ysp2p and its paralog Lam4p specifically bind sterols, and Ysp2p, Lam4p and their homologs Ysp1p and Sip3p target punctate ER-PM contact sites distinct from those occupied by known ER-PM tethers. Sterols 70-77 Ysp2p Saccharomyces cerevisiae S288C 24-29 26001273-4 2015 The activity of Ysp2p, reflected in amphotericin-sensitivity assays, requires its second StART-like domain to be positioned so that it can reach across ER-PM contacts. Amphotericin B 36-48 Ysp2p Saccharomyces cerevisiae S288C 16-21 26001273-5 2015 Absence of Ysp2p, Ysp1p or Sip3p reduces the rate at which exogenously supplied sterols traffic from the PM to the ER. Sterols 80-87 Ysp2p Saccharomyces cerevisiae S288C 11-16 32564734-8 2020 The UPC2-1 mutation in the transcription factor UPC2 gene, which leads to the excessive accumulation of sterols in the cell, promotes cell survival in the presence of the pheromone and shows additivity with the LAM2 deletion. Sterols 104-111 Ysp2p Saccharomyces cerevisiae S288C 211-215 32564734-10 2020 We have found that the deletion of ergosterol biosynthesis genes ERG2 and ERG6 reduces the effect of LAM2 deletion. Ergosterol 35-45 Ysp2p Saccharomyces cerevisiae S288C 101-105 32564734-11 2020 Deletion of LAM2 in the Deltaerg4 strain lacking the gene of the last step of ergosterol biosynthesis, significantly increased the proportion of dead cells and decreased the growth rate of the yeast suspension culture even in the absence of the pheromone. Ergosterol 78-88 Ysp2p Saccharomyces cerevisiae S288C 12-16 32564734-12 2020 We suggest that the absence of the effect of LAM2 deletion in the Deltaerg6 and Deltaerg2 strains indicates the inability of Lam2p to transport some ergosterol biosynthesis intermediates, such as lanosterol. Ergosterol 149-159 Ysp2p Saccharomyces cerevisiae S288C 125-130 29927351-3 2018 Here we document that Ysp2 and its paralogue Lam4/Ltc3 are authentic Ypk1 substrates in vivo and show using genetic and biochemical criteria that Ypk1-mediated phosphorylation inhibits the ability of these proteins to promote retrograde transport of sterols from the PM to the ER. Sterols 250-257 Ysp2p Saccharomyces cerevisiae S288C 22-26 29339490-4 2018 Here, we determined the crystal structures of the yeast Lam6 pleckstrin homology (PH)-like domain and the SDs of Lam2 and Lam4 in the apo form and in complex with ergosterol. Sodium Dodecyl Sulfate 106-109 Ysp2p Saccharomyces cerevisiae S288C 113-117 29339490-4 2018 Here, we determined the crystal structures of the yeast Lam6 pleckstrin homology (PH)-like domain and the SDs of Lam2 and Lam4 in the apo form and in complex with ergosterol. Ergosterol 163-173 Ysp2p Saccharomyces cerevisiae S288C 113-117 27227887-5 2016 These phenotypes were rescued by TORC1 inhibition using pharmacological or genetic means, and the loss of Lam2, Gtr1, Gtr2, Npr2 or Npr3 disinhibited TORC1 activity under nitrogen depletion, as measured by Rps6 phosphorylation. Nitrogen 171-179 Ysp2p Saccharomyces cerevisiae S288C 106-110 27227887-6 2016 Consistently, overexpression of GDP-locked Gtr1S20L or GTP-locked Gtr2Q60L, which suppress TORC1 activity in budding yeast, rescued the growth defect of Deltagtr1 cells or Deltagtr2 cells, respectively, and the loss of Lam2, Npr2 or Npr3 similarly diminished the vacuolar localization and the protein levels of Gtr1 and Gtr2. Guanosine Diphosphate 32-35 Ysp2p Saccharomyces cerevisiae S288C 219-223 27227887-8 2016 These findings suggest that Lam2 and Npr2-Npr3 function together as a tether for GDP-bound Gtr1 to the vacuolar membrane, thereby suppressing TORC1 activity for multiple cellular functions. Guanosine Diphosphate 81-84 Ysp2p Saccharomyces cerevisiae S288C 28-32
