Amyloid-beta peptide species ending at positions 40 and 42 (Abeta40, Abeta42) are generated by the proteolytic processing of the Alzheimer's amyloid precursor protein (APP). Abeta peptides accumulate in the brain early in the course of Alzheimer's disease (AD), especially Abeta42. The cytoplasmic domain of APP regulates intracellular trafficking and metabolism of APP and its carboxyl-terminal fragments (CTFalpha, CTFbeta). The role of protein phosphorylation in general, and that of the phosphorylation state of APP at threonine-668 (Thr668) in particular, has been investigated in detail by several laboratories (including our own). Some investigators have recently proposed that the phosphorylation state of Thr668 plays a pivotal role in governing brain Abeta levels, prompting the current study.
