AKAP5
May anchor the PKA protein to cytoskeletal and/or organelle-associated proteins, targeting the signal carried by cAMP to specific intracellular effectors. Association with to the beta2-adrenergic receptor (beta2-AR) not only regulates beta2-AR signaling pathway, but also the activation by PKA by switching off the beta2-AR signaling cascade. Binding protein for dimer of the RII-beta regulatory subunit of cAMP-dependent protein kinase (PKA) and also for the protein kinase C (PKC) and the phosphatase calcineurin (PP2B). Each enzyme is inhibited when bound to the anchoring protein. Also binds the beta2-adrenergic receptor. Part of a complex containing AKAP5, ADCY5, ADCY6 AND PDE4C. Interacts with ADCY8, and enhances its phosphorylation at lipid rafts. Predominantly in the cerebral cortex and the postsynaptic densities of the forebrain, and to a lesser extent in adrenal medulla, lung and anterior pituitary.
