Protein

Protein-tyrosine-phosphatase PTP1

Gene

PTP1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Protein-tyrosine-phosphatase that dephosphorylates and probably inhibits MPK6 in non-oxidative stress conditions. In association with MKP1, represses salicylic acid (SA) and camalexin biosynthesis, thus modulating defense response. May also repress MPK3. Dephosphorylates and inactivates MPK4 in vitro.4 Publications

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.PROSITE-ProRule annotation

Enzyme regulationi

Inhibited by hydrogen peroxide.1 Publication
