Dual specificity protein phosphatase 23 (DUSP23)

Protein phosphatase that mediates dephosphorylation of proteins phosphorylated on Tyr and Ser/Thr residues. In vitro, it may dephosphorylate p44-ERK1 (MAPK3) but not p54 SAPK-beta (MAPK10) in vitro.

Able to increase activation of JNK and p38 (MAPK14). .
