cAMP export by ABCC4 is critical for localized signaling. Here, the authors revealed that PKA activation drives ABCC4 to the plasma membrane and organizes a PDZ-dependent protein network with actin cytoskeleton and scaffolds, like SCRIB, that stabilize the transporter and optimize cAMP efflux. Furthermore, the authors show that the potent ABCC4 inhibitor Ceefourin 2 disrupts this network, revealing a non-canonical mechanism of ABCC4 inhibition.
