General annotation (Comments)

Function

Enzyme with a broad specificity. Negatively regulates TGF-beta signaling through dephosphorylating SMAD2 and SMAD3, resulting in their dissociation from SMAD4, nuclear export of the SMADs and termination of the TGF-beta-mediated signaling By similarity. Dephosphorylates PRKAA1 and PRKAA2. Plays an important role in the termination of TNF-alpha-mediated NF-kappa-B activation through dephosphorylating and inactivating IKBKB/IKKB By similarity.

Catalytic activity

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

Cofactor

Binds 2 magnesium or manganese ions per subunit.

Subunit structure

Monomer By similarity. Interacts with SMAD2; the interaction dephosphorylates SMAD2 in its C-terminal SXS motif resulting in disruption of the SMAD2/SMAD4 complex, SMAD2 nuclear export and termination of the TGF-beta-mediated signaling. Interacts with SMAD2; the interaction dephosphorylates SMAD2 in its C-terminal SXS motif resulting in disruption of the SMAD2/SMAD4 complex, SMAD2 nuclear export and termination of the TGF-beta-mediated signaling By similarity. Interacts with the phosphorylated form of IKBKB/IKKB By similarity.

Subcellular location

Nucleus By similarity. Cytoplasmcytosol By similarity. Membrane By similarity. Note: Weakly associates at the membrane and N-myristoylation mediates the membrane localization By similarity.

Post-translational modification

N-myristoylation is essential for the recognition of its substrates for dephosphorylation By similarity.

Sequence similarities

Belongs to the PP2C family.
