Description générale
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).
Application
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.
Actions biochimiques/physiologiques
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).

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

Ca2+/calmodulin-dependent protein kinase kinase (CaMKK) activates particular multifunctional kinases, including CaMKI, CaMKIV, and 5'AMP-activated protein kinase (AMPK), resulting in the regulation of various Ca2+-dependent cellular processes, including neuronal, metabolic, and pathophysiological pathways. We developed and characterized a novel pan-CaMKK inhibitor
