cyclic AMP-dependent protein kinase

[¦sī·klik ¦ā¦em¦pē di¦pen·dənt ‚pro‚tēn ′kī‚nās]
(biochemistry)
A serine/threonine protein kinase that phosphorylates a variety of substrates and regulates many important processes such as cell growth and differentiation and the flow of ions across the cell membrane. Also known as protein kinase A; PKA.

The mentioned enzyme is a part of the Ser/Thr protein kinase family, whose function is to phosphorylate a hydroxyl (-OH) group of serine or threonine in proteins with the help of cAMP-dependent protein kinase which activates it through phosphorylation [6, 7].
The MOD_PKA_2 motifs matched with amino acid residues CRVSGGE (279-285) that is part of a functional residue of secondary preference for PKA-type AGC kinase phosphorylation in cytosol, nucleus, and cAMP-dependent protein kinase complex.
