General annotation (Comments)
| Function | Protein phosphatase inhibitor that specifically inhibits protein phosphatase 2A (PP2A) during mitosis. When phosphorylated at Ser-67 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 By similarity. Also acts as a stimulator of insulin secretion by interacting with sulfonylurea receptor (ABCC8), thereby preventing sulfonylurea from binding to its receptor and reducing K(ATP) channel currents. Ref.1 |
| Subunit structure | Interacts (when phosphorylated at Ser-67) with PPP2R2D By similarity. Interacts with ABCC8. Interacts with SNCA; interaction is disrupted when phosphorylated at Ser-109. Ref.13 Ref.14 |
| Subcellular location | Cytoplasm By similarity. |
| Tissue specificity | Widely expressed with high levels in skeletal muscle and brain and lower levels in the pancreas. Ref.1 Ref.3 |
| Post-translational modification | Phosphorylation at Ser-67 by GWL during mitosis is essential for interaction with PPP2R2D (PR55-delta) and subsequent inactivation of PP2A By similarity. Phosphorylated by PKA. Ref.1 Ref.14 |
| Sequence similarities | Belongs to the endosulfine family. |
