Greater than 95% as determined by SDS-PAGE.

PKA regulatory subunit-II alpha is supplied at a concentration of 0.37mg/ml in 20mM MES, 150mM NaCl, 2mM EDTA, 2mM EGTA, 1mM BME and 50% glycerol. Sterile Filtered clear solution.

PKA should be stored at 4 degree C if entire vial will be used within 1 week. For long term storage below -20 degree C.Avoid multiple freeze-thaw cycles.

Inhibitory Activity: The cAMP-Dependent Protein Kinase, regulatory subunit RIIa reversibly inhibits the catalytic subunit Ca of the cAMP-dependent protein kinase PKA. The inhibition of the catalytic subunit can be reversed by the addition of the second messenger cAMP (> 1uM)

Description: The recombinant PKA regulatory subunit II-a is a dimeric 90 kDa protein. Protein Kinase A is purified by proprietary chromatographic techniques. Introduction: cAMP-dependent PKA is a ubiquitous serine/theonine protein kinase present in a variety of tissues (e.g. brain, skeletal muscle, heart). The intracellular cAMP level regulates cellular responses by altering the interaction between the catatytic C and regulatory R subunits of PKA. The inactive tetrameric PKA holoenzyme R2C2 is activated when cAMP binds to R2, which dissociates the tetramer to R2 cAMP 4 and two active catalytic subunits. Free Catalytic subunits of PKA can phosphorylate a wide variety of intracellular target proteins. In response to hormone- induced high cAMP levels, PKA phosphorylates glycogen synthetase (inhibition of the enzyme activity) and phosphorylase kinase to block glycogen synthesis. Different isoforms of catalytic and regulatory subunits suggest specific functions.
