Protein Structure

UniProt Annotation

Function

Protein phosphatase which regulates actin filament dynamics. Dephosphorylates and activates the actin binding/depolymerizing factor cofilin, which subsequently binds to actin filaments and stimulates their disassembly. Inhibitory phosphorylation of cofilin is mediated by LIMK1, which may also be dephosphorylated and inactivated by this protein. {ECO:0000269PubMed:14531860}.

Subcellular Localization

Cytoplasm, cytoskeleton {ECO:0000269PubMed:14531860}. Cell junction, focal adhesion {ECO:0000269PubMed:14531860}. Note=Colocalizes with filamentous actin in the cytoplasm and the cell periphery. Also localizes to focal adhesions.

Disease Associations

Tissue Specificity

Expressed in brain, heart, liver, skeletal muscle, testis and thymus. Also expressed at lower levels in kidney, small intestine and spleen. {ECO:0000269PubMed:14531860}.
