AbstractThe presenilin proteins are involved in the proteolytic processing of transmembrane proteins such as Notch/lin-12 and the β-amyloid precursor protein (βAPP). Mutation of a conserved cysteine (Cys60Ser) in the C. elegans presenilin sel-12 has a loss-of-function effect on Notch/lin-12 processing similar to that of null mutations in sel-12. In contrast, in mammalian cells, most missense mutations increase γ-secretase cleavage of βAPP. We report here that mutation of this conserved cysteine (Cys92Ser) in human presenilin 1 confers a loss-of-function effect in C. elegans, but causes increased Aβ42 secretion in mammalian cells. These data suggest that the role of presenilins in Notch/lin-12 signalling and βAPP processing are either separately regulated activities or independent activities of the presenilins.
