cascades. By contrast, the Notch signalling pathway uses a relatively direct mechanism, in

translocates to the nucleus. This critical cleavage is mediated by the γ-secretase complex,

Abstract
Many cell-surface receptors transmit signals to the nucleus through complex protein cascades. By contrast, the Notch signalling pathway uses a relatively direct mechanism, in which the intracellular domain of the receptor is liberated by intramembrane cleavage and translocates to the nucleus. This critical cleavage is mediated by the γ-secretase complex, and new findings reveal that this mechanism is used by various receptors, although many questions remain about the biochemical details.
