• Information
  • Symbol: OsEXO1
  • MSU: LOC_Os01g56940
  • RAPdb: Os01g0777300
• Publication
  • Rice exonuclease-1 homologue, OsEXO1, that interacts with DNA polymerase lambda and RPA subunit proteins, is involved in cell proliferation, 2008, Plant Mol Biol.
  • Overexpression of OsRecQl4 and/or OsExo1 enhances DSB-induced homologous recombination in rice, 2012, Plant Cell Physiol.
• Genbank accession number
  • AB179769
• Key message
  • Inhibition of cell proliferation by removal of sucrose from the medium or by the addition of cell cycle inhibitors decreased OsEXO1 expression
  • The transcript of OsEXO1 is highly expressed in meristematic tissues and panicles
• Connection
  • OsEXO1, OsRPA2~OsRPA32-1, Rice exonuclease-1 homologue, OsEXO1, that interacts with DNA polymerase lambda and RPA subunit proteins, is involved in cell proliferation, Yeast two-hybrid analysis shows that OsEXO1 interacted with rice DNA polymerase lambda (OsPol lambda), the 70 kDa subunit b of rice replication protein A (OsRPA70b), and the 32 kDa subunit 1 of rice replication protein A (OsRPA32-1)
  • OsEXO1, OsRecQl4, Overexpression of OsRecQl4 and/or OsExo1 enhances DSB-induced homologous recombination in rice, Here, we demonstrate that overexpression of rice proteins OsRecQl4 (BLM counterpart) and/or OsExo1 (Exo1 homolog) can enhance DSB processing, as evaluated by recombination substrate reporter lines in rice
