Amyloid Precursor Protein (APP) is an integral membrane protein with a large ectodomain, a transmembrane domain, and a short cytoplasmic tail.
APP is proteolytically cleaved by b-secretase (BACE) to generate the APP N-terminal fragment (sbAPP) with Mr100kD and a C-terminal fragment (C99) with Mr12kD.
The smaller 12kD fragment can be further cleaved by g-secretase, an enzyme activity recently attributed to presenilin-2.
This second cleavage produces the insoluble b-amyloid (Ab), a peptide of ~4kD.
The accumulation of b-amyloid in intracellular neurofibrillary tangles and extracellular plaques is observed in the brains of Alzheimer's disease patients and Downs's Syndrome patients.
The APP Thr668 phosphorylated form exists in adult rat brain and correlates with cultured neuronal differentiation.
