General annotation (Comments)

Function

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

Catalytic activity

A phosphoprotein + H2O = a protein + phosphate.

Cofactor

Binds 2 magnesium or manganese ions per subunit By similarity.

Subunit structure

Heterotrimer. Interacts with PAX1 and ARHGEF6 (or ARHGEF7) By similarity.

Subcellular location

Nucleus. Cytoplasm. Note: A truncated form, major form, with the C-terminal part missing, is mostly found in the cytoplasm and a little in the nucleus throughout the central nervous system. Although in some large neurons, the full length, minor form, is found in the nucleus. Ref.1 Ref.2 Ref.3

Tissue specificity

Highly expressed in brain especially in hippocampus, thalamus and midbrain and to a lower extent in heart and spinal cord. Weakly expressed in testis. A very slow signal is also observed in heart, kidney and liver. Ref.1 Ref.2

Sequence similarities

Belongs to the PP2C family.

Contains 1 PP2C-like domain.
