    basic FUNCTION
  • can serve as a biomarker in particular for testicular seminomas and might be causally related to the disease
  • RAD9A, RAD9B plays a role in locating Claspin to sites of DNA damage, facilitating its role during the CHEK1-mediated checkpoint response
  • migrates to nucleoli after nucleolar stress in an ATR- and JNK-dependent manner, in a newly described nucleolar domain structure containing CDKN1A
  • relationship between RAD9B and pathways for checkpoints, stress response and nucleolar function
    • CELLULAR PROCESS protein, ubiquitin dependent proteolysis
