Figure 2. Subcellular targeting of PKA and other signaling proteins by AKAPs.
A) Left, schematic representation of different converging signaling pathways leading to adenylyl cyclase production of cAMP and activation of the PKA holoenzyme. Right, schematic regulation of the AKAP-anchored PKA holoenzyme. B) Examples of AKAP organized glutamate receptor and ion channel signaling complexes. Top, AKAP79/150 organized signaling complexes. Bottom, Yotiao, MAP2, and AKAP15/18 organized signaling complexes.
