DUN1/YDL101C Summary Help

Standard Name DUN1 1
Systematic Name YDL101C
Feature Type ORF, Verified
Description Cell-cycle checkpoint serine-threonine kinase; required for DNA damage-induced transcription of certain target genes, phosphorylation of Rad55p and Sml1p, and transient G2/M arrest after DNA damage; Mec1p and Dun1p function in same pathway to regulate both dNTP pools and telomere length; also regulates postreplicative DNA repair (2, 3, 4, 5, 6)
Name Description DNA-damage UNinducible 7
