Localization:  DUN1 localization details
  • nucleus
Remarks:
  • necessary for induction of Rnr3p and DNA repair genes after DNA damage
  • a high basal level of DIN7 expression is found in strains in which the DUN1 gene was inactivated by transposon insertion
  • Dun1 may be a negative regulator of the DIN7 gene expression
  • the human fork head transcription factor CHES1 suppress checkpoint defective strains including mec1, rad9, rad24, dun1 and rad53
  • expression of CHES1 results in G2 delay after UV irradiation
  • contains a forkhead-associated (FHA) domain
  • phosphorylation increases in response to DNA damage in a Dun1p-dependent manner, suggesting autophosphorylation
  • phosphorylation increases 6-fold after exposure to methylmethanesulfonate
Phenotypes:  Disruption: DUN1 details
  • viable
___
  • null mutants fail to induce Rnr1p, Rnr2p, and Rnr3p but do induce some other DNA repair genes after DNA-damage
  • mutants are sensitive to UV, hydroxyurea, and methylmethanesulfonate, but G2 checkpoint is intact
  • null mutants have reduced DNA damage inducibility of RNR2, RNR3 and RNR4 | PUBMED
  • rnr4-99 dun1-3 mutants have increased RNR3 transcript levels | PUBMED
  • in dun1 deletion mutants the transcript levels of RNR2 and RNR4 are increased after DNA damage | PUBMED
  • Exhibits sensitivity at 5 generations when grown in 10 uM nystatin. | Evi | PUBMED

Overexpression:
  • the lethality of rnr4 dun1 double mutants can be suppressed by overexpression of RNR1 and RNR3 | PUBMED
Suppression:
  • CHES1 is a human fork head transcription factor
