Recombinant Rabbit PP1 Protein

• Cat.No.: PP1-001R
• Product Overview: Recombinant Phosphatase-1 Catalytic Subunit, α-Isoform from rabbit without tag was expressed in E.coli.

Specification

• Species: Rabbit
• Source: E.coli
• 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). 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 PP1α 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).
