An EC 2.7.11.* (protein-serine/threonine kinase) inhibitor that interferes with the action of non-specific serine/threonine protein kinase (EC 2.7.11.1), a kinase enzyme involved in phosphorylation of hydroxy group of serine or threonine. In cell biology, protein kinase A (PKA) is a family of enzymes whose activity is dependent on cellular levels of cyclic AMP (cAMP). PKA is also known as cAMP-dependent protein kinase (EC 2.7.11.11). PKA has several functions in the cell, including regulation of glycogen, sugar, and lipid metabolism. It should not be confused with 5'-AMP-activated protein kinase (AMP-activated protein kinase).
