Protein Phosphatase 1 Inhibitor-2 (PP1 Inhibitor-2), also called PP1 regulatory subunit 2 (PP1R2), I2, and IPP2, binds to PP1 through an RVxF consensus sequence. The complex inactivates PP1, preventing it from dephosphorylating substrates such as glycogen phosphorylase. Unlike PP1 Inhibitor-1, the binding of PP1 Inhibitor-2 is Protein Kinase A phosphorylation-independent. Dissociation of the PP1 Inhibitor-2 complex is enhanced by phosphorylation at T72 by GSK3, ERK, or CDK. Overexpression of PP1 Inhibitor-2 in mouse heart improves cardiac function without changing organ size.

Scientific Data Images for PP1 Inhibitor-2 Antibody
Detection of Human/Mouse/Rat PP1 Inhibitor‑2 by Western Blot.
Western blot shows lysates of Raji human Burkitt's lymphoma cell line and mouse spleen tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat PP1 Inhibitor-2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4719) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for PP1 Inhibitor-2 at approximately 30 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.
Detection of Human PP1 Inhibitor‑2 by Simple WesternTM.
Simple Western lane view shows lysates of Raji human Burkitt's lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for PP1 Inhibitor-2 at approximately 42 kDa (as indicated) using 10 µg/mL of Goat Anti-Human/Mouse/Rat PP1 Inhibitor-2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4719) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.Applications for PP1 Inhibitor-2 Antibody
