Description:
Protein kinase C activity in rat hippocampal membranes and cytosol was determined 1 minute and 1 hour after induction of the synaptic plasticity of long-term potentiation. At 1 hour after long-term potentiation, but not at 1 minute, protein kinase C activity was increased twofold in membranes and decreased proportionately in cytosol, suggesting translocation of the activity. This time-dependent redistribution of enzyme activity was directly related to the persistence of synaptic plasticity, suggesting a novel mechanism regulating the strength of synaptic transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akers, R F -- Lovinger, D M -- Colley, P A -- Linden, D J -- Routtenberg, A -- MH25281/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):587-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003904" target="_blank"〉PubMed〈/a〉
