||Recombinant Bovine PRKAR1A is produced inE. coli.MW=43kDa.
||cAMP-dependent protein kinase type I-alpha regulatory subunit is an enzyme that in humans is encoded by the PRKAR1A gene. cAMP is a signaling molecule important for a variety of cellular functions. cAMP exerts its effects by activating the cAMP-dependent protein kinase A (PKA), which transduces the signal through phosphorylation of different target proteins. The inactive holoenzyme of PKA is a tetramer composed of two regulatory and two catalytic subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits. Four different regulatory subunits and three catalytic subunits of PKA have been identified in humans.
||Liquid. In 10mM potassium phosphate, pH 6.8, containing 150mM NaCl, 14mM 2-mercaptoethanol, 1mM EDTA and 50% glycerol.
|Storage And Stability:
||-80°C. Keep the glycerol stock solution of the enzyme permanently at -20°C while pipetting to avoid loss of inhibitory activity. Avoid freeze/thaw cycles.
