| 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). 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}. |

Composed of two structurally equivalent A and B domains that adopt a dual specificity protein phosphatase (DSP) fold. |
| Similarity: | |
Belongs to the protein-tyrosine phosphatase family. Non- receptor class CDC14 subfamily. {ECO:0000305}. |
