Descripción general

The APP (amyloid precursor protein) gene is mapped to human chromosome 21q21.3.[1] It encodes a integral membrane protein. APPα is a soluble protein generated by sequential cleavage with α and γ secretase.[2]

Aplicación

Human amyloid precursor protein α secreted, has been used in enzyme linked immunosorbent assay (ELISA).[3][4][5]

Acciones bioquímicas o fisiológicas

Amyloid precursor protein α is an α-secretase-cleaved soluble protein that has been shown to have neuroprotective properties. It is derived from amyloid precursor protein. The protein consists of 612 amino acids. Several G protein-coupled receptors are known to activate α-secretase-dependent processing of APP. It has neuroprotective, neurogenic and neurotrophic functions. Amyloid precursor protein a also stimulates gene expression and protein expression.[6]

Forma física

Solution 0.2 μm filtered, in phosphate buffered saline, pH 7.4.

Microglial activation as part of a chronic inflammatory response is a prominent component of Alzheimer's disease. Secreted forms of the beta-amyloid precursor protein (sAPP) previously were found to activate microglia, elevating their neurotoxic potential. To explore neurotoxic mechanisms, we analyzed

A significant fraction of the beta-amyloid precursor protein is proteolytically processed to yield large secreted forms (sAPP). These proteins have pleiotropic effects which potentially involve control of gene expression. We have investigated the influence of sAPP on the class of
