Sprouty, an Intracellular Inhibitor of Ras Signaling
Open accessAbstract
Sprouty was identified in a genetic screen as an inhibitor of Drosophila EGF receptor signaling. The Egfr triggers cell recruitment in the eye, and sprouty- eyes have excess photoreceptors, cone cells, and pigment cells. Sprouty's function is, however, more widespread. We show that it also interacts genetically with the receptor tyrosine kinases Torso and Sevenless, and it was first discovered through its effect on FGF receptor signaling. In contrast to an earlier proposal that Sprouty is extracellular, we show by biochemical analysis that Sprouty is an intracellular protein, associated with the inner surface of the plasma membrane. Sprouty binds to two intracellular components of the Ras pathway, Drk and Gap1. Our results indicate that Sprouty is a widespread inhibitor of Ras pathway signal transduction.

“Four of the validated miR-21 target genes are known negative regulators of the Ras/MEK/ERK pathway: sprouty 1 (Spry1), sprouty 2 (Spry2), B-cell translocation gene 2 (Btg2), and programmed cell death 4 (Pdcd4).”

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.
