Summary

Notch-1 is a member of a conserved family of transmembrane receptors that regulate cell fate decisions during development. A role for presenilins in the regulation of Notch signalling has been suggested by studies of the Caenorhabditis elegans presenilin homolog sel-12. These findings suggest that PS1 may regulate the Notch signaling pathway during development, although the cellular mechanism is unknown. We explore the possibility that PS1 and PS2 may also regulate proteolytic cleavage of Notch-1 intracellular domain. We now report that presenilins are absolutely required for the proteolytic release and nuclear translocation of the Notch-1 intracellular domain.
