Subcellular distribution in cerebral cortex of two proteins phosphorylated by a cAMP-dependent protein kinase.
Open accessAbstract
The subcellular distribution of Proteins Ia and Ib, two proteins which serve as specific substrates for protein kinases present in mammalian brain, was studied in the dog cerebral cortex. Proteins Ia and Ib were found to be most highly enriched in synaptic vesicle fractions; they were also present in postsynaptic density and synaptic membrane fractions in significant amounts. Proteins Ia and Ib present in the synaptic vesicle fraction appear to be similar, if not identical, to those present in the postsynaptic density fraction as judged by several criteria: (a) the ability to serve as substrate for cAMP-dependent protein kinase, (b) electrophoretic mobility in the presence of sodium dodecyl sulfate, (c) extractability with NH4Cl or EGTA, and (d) fragmentation to electrophoretically similar peptides by a purified Staphylococcus aureus protease. In addition, the postsynaptic density fraction has been found to contain cAMP-dependent Protein Ia and Protein Ib kinase activity. The subcellular localization of Proteins Ia and Ib suggests a role for these proteins in the physiology of the synapse.

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.
