설명

일반 설명

Protein Kinase A (PKA) is a serine/threonine kinase, which exists as a tetrameric holoenzyme.

애플리케이션

Protein Kinase A from bovine heart has been used to determine its activity using a molecular beacon probe. It has also been used to study the interaction of staurosporine with the ATP-binding site of kinases.

Protein Kinase A from bovine heart has been used to inhibit the phosphorylation of myosin.

생화학적/생리학적 작용

Many 3′,5′-cyclic AMP dependent protein kinases have been reported. Structural studies (Traugh, J.A., et al., Meth. Enzymol., 38, 290 [1974]) show the presence of at least two subunits, the regulatory subunit and the catalytic subunit. When both units are linked together, the catalytic activity is inhibited. However, when the cyclic-AMP binds to the regulatory subunit, the catalytic subunit is released and can then catalyze the transfer of phosphate from ATP to various proteins.

Protein Kinase A (PKA) inhibits hormone-sensitive lipase translocation from cytosol to storage droplets and blocks lipolysis. It regulates apoptosis, mitochondrial respiration and ATP synthesis. PKA is modulated by protease calpain.
