cAMP binding to cAMP-dependent protein kinase A causes the regulatory subunits to release the tetrameric complex of regulatory and catalytic subunits. This allows the catalytic subunits to phosphorylate multiple targets with specific serine and threonine residues. There is no association with membrane-bound phosphoinositols.
