III, Heyer W.D.; RT "A truncated DNA-damage-signaling response is activated after DSB formation RT in the G1 phase of Saccharomyces cerevisiae."; RL Nucleic Acids Res. 38:2302-2313(2010). CC -!- FUNCTION: Endonuclease that cooperates with the MRX complex in CC processing meiotic and mitotic double-strand breaks by allowing the CC endonucleolytic removal of SPO11 from the break sites and ensuring both CC resection and intrachromosomal association of the broken ends. Required CC for proper recovery from checkpoint-mediated cell cycle arrest after CC DNA damage. MRX complex and SAE2 remove a small oligonucleotide(s) from CC the DNA ends to form an early intermediate which is rapidly processed CC by EXO1 and/or SGS1 to generate extensive tracts of single-stranded DNA CC that serve as substrate for RAD51. Plays a transitional role in the CC dissociation of MRE11 from, and the recruitment of RAD52 to, repair CC foci. Ensures that both ends of a DSB participate in a recombination CC event and impairs the formation of palindromic structures in the CC genome. With TEL1, promotes microhomology-mediated end joining (MMEJ) CC but inhibits non-homologous end joining (NHEJ), likely by regulating CC MRE11-dependent ssDNA accumulation at DNA break. SAE2 and MRX are CC particularly important for removal of hairpins, bulky adducts and other CC irregular end structures. Facilitates telomere length reequilibration CC and subsequent checkpoint switch off. Involved in homing efficiency of CC VMA1 intein VDE and in repair of transposon excision sites.

CC -!- PTM: Phosphorylated forms accumulate periodically during the CC unperturbed cell cycle and in response to DNA damage in G2. CC Phosphorylated by MEC1 and TEL1.
