  • Title: Coordination of three signaling enzymes by AKAP79, a mammalian scaffold protein.
    Author: Klauck TM, Faux MC, Labudda K, Langeberg LK, Jaken S, Scott JD.
    Journal: Science; 1996 Mar 15; 271(5255):1589-92. PubMed ID: 8599116.
    Abstract:
    Multivalent binding proteins, such as the yeast scaffold protein Sterile-5, coordinate the location of kinases by serving as platforms for the assembly of signaling units. Similarly, in mammalian cells the cyclic adenosine 3',5'-monophosphate-dependent protein kinase (PKA) and phosphatase 2B [calcineurin (CaN)] are complexed by an A kinase anchoring protein, AKAP79. Deletion analysis and binding studies demonstrate that a third enzyme, protein kinase C (PKC), binds AKAP79 at a site distinct from those bound by PKA or CaN. The subcellular distributions of PKC and AKAP79 were similar in neurons. Thus, AKAP79 appears to function as a scaffold protein for three multifunctional enzymes.
