Protein
Protein phosphatase 2C 37
Gene
PP2CA, AHG3, At3g11410, F24K9.8
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Major negative regulator of abscisic acid (ABA) responses during seed germination and cold acclimation. Confers insensitivity to ABA. Modulates negatively the AKT2/3 activity, which mediates K+ transport and membrane polarization during stress situations, probably by dephosphorylation. Prevent stomata closure by inactivating the S-type anion efflux channel SLAC1 and its activator SRK2E.7 Publications

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Cofactori

Binds 2 magnesium or manganese ions per subunit By similarity.

Enzyme regulationi

Repressed by PYR/PYL/RCAR ABA receptors in an ABA-dependent manner.1 Publication

Interacts with AKT2/AKT3. Interacts with ABA-bounded PYR1, PYL1, PYL2, PYL3, PYL4, PYL9 and PYL12, and with free PYL2, PYL3 and PYL4. Binds to and inactivates SLAC1 and SRK2E. The inactivation of SRK2E does not require phosphatase activity. Interacts with CBL1, CBL2, CBL3, CBL5, and CBL7, but not CBL4, CBL6, and CBL9.5 Publications
