Presenilin 1 mediates protein kinase C dependent alpha-secretase derived amyloid precursor protein secretion and mitogen-activated protein kinase activation in presenilin 1 transfected human embryonic kidney 293 cell.

Abstract

We investigated the role of presenilin 1 (PS1) in the secretion of alpha-secretase derived amyloid precursor protein (sAPP alpha) and associated intracellular signaling pathways. Human embryonic kidney (HEK) 293 cells were transfected with exon 9 deletion (deltaE9) mutant PS1 cDNA in an ecdyson-inducible system. sAPPalpha secretion was lower in the mutant… (More)
