Q: A nonsense mutation changes an amino acid codon into a stop codon. True or False?

Did You Know?

True. NOTCH signaling is unique among major pathways. Activation requires two sequential proteolytic cleavages after ligand binding. The final intramembrane cleavage, catalyzed by the γ-secretase complex, releases the NOTCH Intracellular Domain (NICD). NICD translocates to the nucleus, where it binds to the transcription factor CSL (RBP-Jκ) to activate target gene expression.
