Inhibitor-2 (I-2) exists as a heterodimer with protein phosphatase type-1 (PP1), termed MgATP-dependent phosphatase. I-2 binds and forms an inactive complex with PP1 in its unphosphorylated state. This complex is activated through a series of phosphorylations on serine and threonine residues in I-2 that increases phosphatase activity. Multiple kinases have been implicated in phosphorylation of I-2 at threonine 72, namely GSK-3, cdc2 and ERK1. Casein kinase II phosphorylates I-2 at serine residues, which in turn enhances threonine phosphorylation by GSK-3. Recent evidence has shown that phosphorylation at threonine 72 peaks during prophase of the cell cycle and is localized in the centrosomes. The I-2/PP1 complex also binds neurabin and the kinases Nek2, KPI-2, and Aurora-A. Regulation of I-2/PP1 has been shown to be important in cell cycle, gene expression, ion gating, and neuromodulation.
