Descriptions

Application

Protein Phosphatase-1 Catalytic Subunit, ?-Isoform from rabbit has been used as a standard in protein phosphatase-1 inhibition assay.

Protein Phosphatase-1 Catalytic Subunit, ?-Isoform from rabbit has been used in protein phosphatase reaction and in the digestion of adipocyte extracts.

Biochem/physiol Actions

Protein phosphatase1 (PP1) is involved in glycogen metabolism and in regulation of muscle contractility. In addition, it is implicated in cell cycle and transcriptional regulation. Recombinant rabbit PP1? has properties in common with the native rabbit muscle protein including size, requirement for Mn²⁺ for activity, specificity for phosphorylase A, and inhibition by okadaic acid, microcystin LR, and phosphatase inhibitor2 (I-2).

General description

Protein phosphatase1 (PP1) is a heterodimeric enzyme with serine/threonine phosphatase activity. It comprises a catalytic subunit and a targeting subunit or a specific protein inhibitor. The targeting subunit determines the enzyme localization, e.g., to glycogen particles (subunit G) or to myofibrils (subunit M).
