Name Dual specificity protein phosphatase CDC14B
Synonyms
  1. CDC14 cell division cycle 14 homolog B
  2. SubName: cDNA FLJ44424 fis, clone UTERU2005621, highly similar to Dual specificity protein phosphatase CDC14B (EC 3.1.3.48)
Gene Name CDC14B
Protein Type Enzyme
Biological Properties
General Function Involved in phosphatase activity
Specific Function Dual-specificity phosphatase involved in DNA damage response. Essential regulator of the G2 DNA damage checkpoint: following DNA damage, translocates to the nucleus and dephosphorylates FZR1/CDH1, a key activator of the anaphase promoting complex/cyclosome (APC/C). Dephosphorylation of FZR1/CDH1 activates the APC/C, leading to the ubiquitination of PLK1, preventing entry into mitosis. Preferentially dephosphorylates proteins modified by proline-directed kinases.
