APP encodes the amyloid precursor protein, a type I transmembrane glycoprotein that is centrally involved in Alzheimer's disease pathogenesis. APP is a member of the APP family, which includes APLP1 and APLP2 in mammals.
Key normal physiological functions include:
APP mutations cause autosomal dominant early-onset Alzheimer's disease through increased amyloid-beta production or altered Aβ aggregation properties:
The amyloid cascade hypothesis posits that Aβ accumulation initiates a pathogenic cascade leading to tau pathology, synaptic loss, and neuronal death.
Individuals with Down syndrome have three copies of APP (due to chromosome 21 trisomy), resulting in:
APP mutations (especially Arctic and Dutch mutations) can cause:
APP is widely expressed in the central nervous system:
The Allen Brain Atlas shows high APP expression in:
