Protein Structure
UniProt Annotation
Function Protein phosphatase inhibitor that specifically inhibits protein phosphatase 2A (PP2A) during mitosis. When phosphorylated at Ser-62 during mitosis, specifically interacts with PPP2R2D (PR55-delta) and inhibits its activity, leading to inactivation of PP2A, an essential condition to keep cyclin-B1-CDK1 activity high during M phase. May indirectly enhance GAP-43 expression (By similarity). {ECO:0000250}.
Subcellular Localization Cytoplasm {ECO:0000250}.
Disease Associations
Tissue Specificity Isoform ARPP-19 is found in all brain regions and also present in non-neuronal tissues. Isoform ARPP-16 is enriched in the caudate nucleus, found in low levels in cerebral cortex.
