    Regulation of NMDA receptors by an associated phosphatase-kinase signaling complex (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-07-03
    Description: Regulation of N-methyl-D-aspartate (NMDA) receptor activity by kinases and phosphatases contributes to the modulation of synaptic transmission. Targeting of these enzymes near the substrate is proposed to enhance phosphorylation-dependent modulation. Yotiao, an NMDA receptor-associated protein, bound the type I protein phosphatase (PP1) and the adenosine 3',5'-monophosphate (cAMP)-dependent protein kinase (PKA) holoenzyme. Anchored PP1 was active, limiting channel activity, whereas PKA activation overcame constitutive PP1 activity and conferred rapid enhancement of NMDA receptor currents. Hence, yotiao is a scaffold protein that physically attaches PP1 and PKA to NMDA receptors to regulate channel activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westphal, R S -- Tavalin, S J -- Lin, J W -- Alto, N M -- Fraser, I D -- Langeberg, L K -- Sheng, M -- Scott, J D -- F32 NS010202/NS/NINDS NIH HHS/ -- GM 48231/GM/NIGMS NIH HHS/ -- NS10202/NS/NINDS NIH HHS/ -- NS10543/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1999 Jul 2;285(5424):93-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Vollum Institute, Oregon Health Sciences University, 3181 S.W.

    Coordination of three signaling enzymes by AKAP79, a mammalian scaffold protein (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-03-15
    Description: 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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klauck, T M -- Faux, M C -- Labudda, K -- Langeberg, L K -- Jaken, S -- Scott, J D -- CA538841/CA/NCI NIH HHS/ -- GM48231/GM/NIGMS NIH HHS/ -- GM50152/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1996 Mar 15;271(5255):1589-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland, 97201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8599116" target="_blank"〉PubMed〈/a〉

    Cell signaling in space and time: where proteins come together and when they're apart (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-08
    Description: Signal transduction can be defined as the coordinated relay of messages derived from extracellular cues to intracellular effectors. More simply put, information received on the cell surface is processed across the plasma membrane and transmitted to intracellular targets. This requires that the activators, effectors, enzymes, and substrates that respond to cellular signals come together when they need to.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3041271/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3041271/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scott, John D -- Pawson, Tony -- 57793/Canadian Institutes of Health Research/Canada -- 6849/Canadian Institutes of Health Research/Canada -- GM48231/GM/NIGMS NIH HHS/ -- R37 GM048231/GM/NIGMS NIH HHS/ -- R37 GM048231-19/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1220-4. doi: 10.1126/science.1175668.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Howard Hughes Medical Institute, Box 357750, University of Washington School of Medicine, Seattle, WA 98195, USA. scottjdw@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965465" target="_blank"〉PubMed〈/a〉
