Géninformáció

Általános leírás

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).

Alkalmazás

Protein Phosphatase-1 Catalytic Subunit, α-Isoform from rabbit has been used as a standard in protein phosphatase-1 inhibition assay.
Protein Phosphatase-1 Catalytic Subunit, α-Isoform from rabbit has been used in protein phosphatase reaction and in the digestion of adipocyte extracts.

Biokémiai/fiziológiai hatások

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).

Ca2+/calmodulin-dependent protein kinase kinase β (CaMKKβ) acts as a regulatory kinase that phosphorylates and activates multiple downstream kinases including CaMKI, CaMKIV, 5'AMP-activated protein kinase (AMPK) and protein kinase B (PKB), resulting in regulation of wide variety of Ca2+-dependent physiological responses

One important regulatory mechanism in the control of phosphorylation events is the subcellular location of phosphatases of kinases. Several serine/threonine phosphatases and kinases have now been shown to be associated with targeting subunits; these contribute to the organization and specificity

The catalytic subunit of rabbit skeletal muscle protein phosphatase-1 was expressed in Escherichia coli. Expression of phosphatase-1 in the pET3a vector, which is based on the use of the T7 promoter, resulted in the expression of the enzyme as an
