Discovery
Dock180 was identified, using a far-western blotting approach, as a binding partner of the adaptor protein Crk that was able to induce morphological changes in 3T3 fibroblasts. Subsequently it was reported that Dock180 was able to activate the small GTP-binding protein (G protein) Rac1 and this was later shown to happen via its ability to act as a GEF.

Famous quotes containing the word discovery:
“Your discovery of the contradiction caused me the greatest surprise and, I would almost say, consternation, since it has shaken the basis on which I intended to build my arithmetic.... It is all the more serious since, with the loss of my rule V, not only the foundations of my arithmetic, but also the sole possible foundations of arithmetic seem to vanish.”
—Gottlob Frege (1848–1925)
“The gain is not the having of children; it is the discovery of love and how to be loving.”
—Polly Berrien Berends (20th century)
