|Detection of Human/Mouse/Rat PP1 Catalytic Subunit, by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and C2C12 mouse myoblast cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat PP1 Catalytic Subunit, Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3000) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for PP1 at approximately 39 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.|
Protein Phosphatase 1, also known as PP1 and PPP1, is an enzyme that removes phosphate groups attached to serine or threonine residues in proteins. The holoenzyme is composed of two subunits, a catalytic subunit (PP1ca) that is highly conserved throughout evolution, and a wide variety of regulatory subunits that target the enzyme to specific subcellular compartments and proteins. The catalytic subunit is ubiquitously expressed in tissues and cell lines.
