TOMAHAQ-based targeted proteomics relies on heavy-labeled reference peptides for multi-plexed quantification of peptides of interest within a set of samples. The APP amyloid precursor protein is thought to be proteolytically processed within the endolysosomal system by β-secretase and ϒ-secretase to yeild various forms of Aβ. To quantitatively track APP products, we describe a protocol for design and generation of synthetic reference peptides for TOMAHAQ analysis. We also include reference peptides for the extracellular and cytosolic domains.

Memapsin 2

Mempasin 2, a ϐ-secretase, is the membrane-anchored aspartic protease that initiates the cleavage of amyloid precursor protein leading to the production of ϐ-amyloid and the onset of Alzheimer's disease. Thus memapsin 2 is a major therapeutic target for the development of inhibitor drugs for the disease. Many biochemical tools, such as the specificity and crystal structure, have been established and have led to the design of potent and relatively small transition-state inhibitors. Although developing a clinically viable mempasin 2 inhibitor remains challenging, progress to date renders hope that memapsin 2 inhibitors may ultimately be useful for therapeutic reduction of ϐ-amyloid.
