FUNCTION: Targets the cAMP-dependent protein kinase (PKA) to the plasma membrane, and permits functional coupling to the L-type calcium channel. The membrane-associated form reduces epithelial sodium channel (ENaC) activity, whereas the free cytoplasmic form may negatively regulate ENaC channel feedback inhibition by intracellular sodium. {ECO:0000269|PubMed:10613906, ECO:0000269|PubMed:17244820, ECO:0000269|PubMed:9545239}.
