Bound for destruction: Ubiquitination protects against improper Notch signaling

The Notch pathway is an important molecular signaling mechanism whose existence has beenknown, or at least hinted at, for nearly a century since theidentification of a mutant strain of Drosophila fruit flies with“notched?wings in Thomas Hunt Morgan’s lab in 1910. Later studiesreveale...
