Role of Ca2+‐stimulated adenylyl cyclases in LTP and memory formation

Poser, Steve, Storm, Daniel R.·2001·International Journal of Developmental Neuroscience

Abstract

Studies with invertebrates and vertebrates have strongly implicated the CREB/CRE transcriptional pathway in long‐term memory (LTM) and transcriptionally‐dependent L‐LTP. It is hypothesized that LTM and L‐LTP are both dependent upon a Ca 2+ signal generated through activation of NMDA receptors. This review discusses evidence that Ca 2+ signals generated through activation of NMDA receptors coactivate the Erk/MAP kinase and cAMP signal transduction pathways. It is hypothesized that activation of these two regulatory pathways increases the transcription of a family of genes through the CREB/CRE transcriptional pathway. Gene disruption studies have shown that Ca 2+ activated adenylyl cyclases play a critical role in generating the cAMP signal required for LTM and L‐LTP. Although cAMP may be required for several events in this complex signal transduction cascade, one of the major roles of cAMP may be to support nuclear translocation of Erk/MAP kinase in hippocampal neurons.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
