24195737 The results show that contrary to initial observations PPP1R2-related pseudogenes are not simple bystanders of the evolutionary process but may rather be at the origin of genes with novel functions.
23506001 The potential phosphosites in PPP1R2 are substituted by non-phosphorylable residues, T73P and S87R, in PPP1R2P3.
21714498 Pin1 and phosphatase inhibitor-2 are conserved among eukaryotes from yeast to humans and make an ancient partnership that provides a means for regulating Pin1 specificity and function.
19036150 Results suggest that phosphatase inhibitor 2 localizes to the primary cilium of human retinal epithelial cells where it affects both Ser/Thr phosphorylation and is required for full tubulin acetylation.
18716057 Conserved together throughout eukaryotic evolution, I-2, PP1 and Aurora B function interdependently during mitosis.
16987514 These results indicate that the protein phosphatase-1/inhibitor-2 complex differentially regulates GSK3 dephosphorylation induced by KCl and that GSK3 activity regulates SERCA2 levels.
16627625 Studies in hamster indicate that modulation of type 1 protein phosphatase (PP1) activity by inhibitor-2 (INH-2) provides a potential new treatment for heart failure without activating protein kinase A (PKA) signaling.
12761178 first demonstration that glycogen synthase kinase-3beta associates with PP1C/I-2 complex and phosphorylates I-2 at T72 in intact cells
12393858 PP1C and Inh2 bind to KPI2 to form a regulatory complex that is localized to membranes
12221103 Inh2 can enhance the kinase activity of the Nek2.PP1C complex via inhibition of phosphatase activity to initiate centrosome separation
