Abstract
Threonine668(thr668) within the carboxy‐terminus of the Alzheimer's disease amyloid precursor protein (APP) is a knownin vivophosphorylation site. Phosphorylation of APPthr668is believed to regulate APP function and metabolism. Thr668precedes a proline, which suggests that it is targeted for phosphorylation by proline‐directed kinase(s). We have investigated the ability of four major neuronally active proline‐directed kinases, cyclin dependent protein kinase‐5, glycogen synthase kinase‐3β, p42 mitogen‐activated protein kinase and stress‐activated protein kinase‐1b, to phosphorylate APPthr668and report here that SAPK1b induces robust phosphorylation of this site bothin vitroandin vivo. This finding provides a molecular framework to link cellular stresses with APP metabolism in both normal and disease states.
