Rapid formation of inositol 1,3,4,5-tetrakisphosphate following muscarinic receptor stimulation of rat cerebral cortical slices

Abstract

Carbachol stimulation of muscarinic receptors in rat cortical slices prelabelled with myo-[2-3H]inositol caused the rapid formation of a novel inositol polyphosphate. Evidence derived from its chromatographic behaviour, and from the structure of the products formed in partial dephosphorylation experiments, suggests that it is probably D-myo-inositol 1,3,4,5-tetrakisphosphate. An enzyme in human red cell membranes specifically removes the 5-phosphate from it to form inositol 1,3,4-trisphosphate. It is suggested that inositol 1,3,4,5-tetrakisphosphate is likely to be a second messenger, and that it is the precursor of inositol 1,3,4-trisphosphate and possibly of inositol 1,4,5-trisphosphate.

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.
