11. Today, this cAMP-dependent protein kinase is more simply noted as PKA. 12. The protein encoded by this gene belongs to the protein kinase C superfamily. 13. Cyclic AMP-dependent protein kinase is unique in its mechanism of activation. 14. Mezerein and other phorbol esters interact with protein kinase C ( PKC ). 15. Its overall structure is similar to members of the eukaryotic protein kinase family. 16. This gene encodes a member of the Ser / Thr protein kinase family. 17. These signaling proteins include type II protein kinase A, phosphodiesterase 4D3. 18. MAP2K1 is also known as MEK1 ( see Mitogen-activated protein kinase kinase ). 19. AMP-activated protein kinase regulation of the glucose transporter GLUT4 occurs by phosphorylation of HDAC5. 20. These enzymes are members of the serine / threonine-specific protein kinase family ( ).
