Ligand-dependent G Protein Coupling Function of Amyloid Transmembrane Precursor
Open accessAbstract
Amyloid precursor protein (APP), a transmembrane precursor of beta-amyloid, possesses a function whereby it associates with G(o) through its cytoplasmic His657-Lys676. Here we demonstrate that APP has a receptor function. In phospholipid vesicles consisting of baculovirally made APP695 and brain trimeric G(o), 22C11, a monoclonal antibody against the extracellular domain of APP, increased GTP gamma S binding and the turnover number of GTPase of G(o) without affecting its intrinsic GTPase activity. This effect of 22C11 was specific among various antibodies and was observed neither in G(o) vesicles nor in APP695/Gi2 vesicles. In APP695/G(o) vesicles, synthetic APP66-81, the epitope of 22C11, competitively antagonized the action of 22C11. Monoclonal antibody against APP657-676, the G(o) binding domain of APP695, specifically blocked 22C11-dependent activation of G(o). Therefore, APP has a potential receptor function whereby it specifically activates G(o) in a ligand-dependent and ligand-specific manner.

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.
