RGS Proteins and Signaling by Heterotrimeric G Proteins
Open accessAbstract
A ubiquitously employed mechanism for signal transduction involves ligand binding to a cell surface receptor coupled to a heterotrimeric guanine nucleotide-binding protein (G protein). Receptor activation stimulates nucleotide exchange and dissociation of the G protein, releasing the Gα subunit in its GTP-bound state from the Gβγ complex. The released subunits can stimulate a variety of target (effector) enzymes (1), thereby eliciting biochemical responses and changes in cellular physiology. Hundreds of G protein-coupled receptors have been identified (2, 3).

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.
