Protein Structure
UniProt Annotation
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). {ECO:0000250}.
Subcellular Localization Nucleus {ECO:0000250}. Cytoplasm, cytosol {ECO:0000250}. Membrane {ECO:0000250}. Note=Weakly associates at the membrane and N-myristoylation mediates the membrane localization. {ECO:0000250}.
