Hydroxyurea 83-94 protein kinase MEC1 Saccharomyces cerevisiae S288C 9-13 23045388-5 2012 In fact, delaying either the G(1)/S transition or spindle elongation in mec1 and rad53 mutants allows their survival both after exposure to hydroxyurea and under unperturbed conditions. Hydroxyurea 140-151 protein kinase MEC1 Saccharomyces cerevisiae S288C 72-76 19805819-7 2009 In contrast, cells with the mec1-1 sml1-1 mutations suffer from severely impaired replication resumption upon removal of hydroxyurea. Hydroxyurea 121-132 protein kinase MEC1 Saccharomyces cerevisiae S288C 28-34 21172804-5 2011 Contrary to the expectation that each factor would contribute to fragile site expression in an independent manner, we show that rrm3Delta and high concentrations of HU suppressed RSZ expression in mec1-4ts cells. Hydroxyurea 165-167 protein kinase MEC1 Saccharomyces cerevisiae S288C 197-201 10747050-4 2000 Deleting PTC2 specifically suppresses the hydroxyurea hypersensitivity of mec1 mutants and the lethality of mec1Delta. Hydroxyurea 42-53 protein kinase MEC1 Saccharomyces cerevisiae S288C 74-78 11497275-3 2001 RESULTS: Hydroxyurea (20 mM) decreased proliferation rates only in mec1 mutant and deletion strains. Hydroxyurea 9-20 protein kinase MEC1 Saccharomyces cerevisiae S288C 67-71 10733584-7 2000 Hydroxyurea inhibits late-origin firing in S. cerevisiae, and the checkpoint genes, RAD53 and MEC1, are involved in this inhibition. Hydroxyurea 0-11 protein kinase MEC1 Saccharomyces cerevisiae S288C 94-98 11000264-4 2000 We now demonstrate that Rfa1p is phosphorylated in response to various forms of genotoxic stress, including radiation and hydroxyurea exposure, and further show that phosphorylation of Rfa1p is dependent on the central checkpoint regulator Mec1p. Hydroxyurea 122-133 protein kinase MEC1 Saccharomyces cerevisiae S288C 240-245 11000264-5 2000 Analysis of the requirement for other checkpoint genes indicates that different mechanisms mediate radiation- and hydroxyurea-induced Rfa1p phosphorylation despite the common requirement for functional Mec1p. Hydroxyurea 114-125 protein kinase MEC1 Saccharomyces cerevisiae S288C 202-207 34569643-2 2021 Here, we identify a hydroxyurea-induced phosphorylation site on Mec1, Mec1-S1991, that contributes to the eviction of RNAPII and RNAPIII during replication stress. Hydroxyurea 20-31 protein kinase MEC1 Saccharomyces cerevisiae S288C 64-68 34569643-2 2021 Here, we identify a hydroxyurea-induced phosphorylation site on Mec1, Mec1-S1991, that contributes to the eviction of RNAPII and RNAPIII during replication stress. Hydroxyurea 20-31 protein kinase MEC1 Saccharomyces cerevisiae S288C 70-74 25609572-1 2015 We have previously demonstrated that in Saccharomyces cerevisiae replication, checkpoint inactivation via a mec1 mutation leads to chromosome breakage at replication forks initiated from virtually all origins after transient exposure to hydroxyurea (HU), an inhibitor of ribonucleotide reductase. Hydroxyurea 237-248 protein kinase MEC1 Saccharomyces cerevisiae S288C 108-112 9927443-8 1999 We propose that the essential function for MEC1 may be the same as its checkpoint function during hydroxyurea treatment, namely, to slow S phase when nucleotides are limiting. Hydroxyurea 98-109 protein kinase MEC1 Saccharomyces cerevisiae S288C 43-47
