Protein Information (annotations from UniProt)

Database IDHIV0008198
UniProt IDO60729
Primary gene name(s)CDC14B
Synonym gene name(s)unknown
Protein nameDual specificity protein phosphatase CDC14B
Protein functionDual-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. Dephosphorylates SIRT2 around early anaphase. 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. {ECO:0000269|PubMed:17488717, ECO:0000269|PubMed:18662541, ECO:0000269|PubMed:9367992}.
Subcellular locationNucleus, nucleolus. Nucleus, nucleoplasm. Note=Following DNA damage, translocates from the nucleolus to the nucleoplasm and interacts with FZR1/CDH1.
