Description_x000D_ General description_x000D_ PP1A is a serine/threonine specific protein phosphatase family which is involved in the regulation of a variety of cellular processes, such as cell division, glycogen metabolism, muscle contractility, protein synthesis, and HIV-1 viral transcription. PP1A is one of the three catalytic subunits of protein phosphatase 1 (PP1). PP1A functions as a suppressor of learning and memory and as a potential mediator of cognitive decline during aging.PP1A is also play a main role in splice site selection and is an important regulator of cardiac function._x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 10 mM glutathione, 0.1 mM EDTA, 0.25 mM DTT, 0.1 mM PMSF, 25% glycerol._x000D_ Preparation Note_x000D_ After opening, aliquot into smaller quantities and store at -70 °C.
