Dual specificity protein phosphatase 23

Gene

Dusp23

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Protein phosphatase that mediates dephosphorylation of proteins phosphorylated on Tyr and Ser/Thr residues. In vitro, it can dephosphorylate p44-ERK1 (MAPK3) but not p54 SAPK-beta (MAPK10) in vitro. Able to enhance activation of JNK and p38 (MAPK14).1 Publication

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.PROSITE-ProRule annotation1 Publication
[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.1 Publication
