Protein
Protein phosphatase 1E
Gene
PPM1E, CAMKN, KIAA1072, POPX1
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Protein phosphatase that inactivates multifunctional CaM kinases such as CAMK4 and CAMK2 By similarity. Dephosphorylates and inactivates PAK. May play a role in the inhibition of actin fiber stress breakdown and in morphological changes driven by TNK2/CDC42. Dephosphorylates PRKAA2 By similarity.1 Publication

Catalytic activityi

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

Cofactori

Binds 2 magnesium or manganese ions per subunit By similarity.
