Descrizione

Descrizione generale

Amyloid beta A4 protein (UniProt P05067; also known as ABPP, Alzheimer disease amyloid protein, Amyloid precursor protein, APP, APPI, Cerebral vascular amyloid peptide, CVAP, PN-II, PreA4, Protease nexin-II) is encoded by the APP (also known as A4, AD1) gene (Gene ID 351) in human. Amyloid precursor protein (APP) is initially produced with a signal peptide sequence (a.a. 1-17), the removal of which yields the mature protein with a large extracellular portion (a.a. 18-699), followed by a transmembrane segment (a.a. 700-723) and a cytoplasmic (a.a. 724-770) tail. APP can be further processed by the α-, β-, and γ-secretases in two alternative processing pathways. In the non-amyloidogenic pathway, APP is first cleaved by the plasma membrane-localized α-secretase to generate an N-terminal extracellular sAPPα fragment (a.a. 18-687) and a membrane-bound C-terminal fragment C83 (CTFα), which can be further cleaved by γ-secretase to produce a non-toxic small peptide p3 and a cytoplasmic APP intracellular domain (AICD). In the amyloidogenic pathway, APP undergoes β-cleavage in BACE-1 (β-site APP-cleaving enzyme)-enriched endosomes to generate an N-terminal extracellular sAPPβ fragment (a.a. 18-671) and a membrane-bound C-terminal fragment C99 (CTFβ). Subsequent cleavage of C99 by γ-secretase releases the amyloid β peptides, Aβ1-42 (672-713) & Aβ1-40 (672-711), and AICD. Aβ accumulation in the cortical and hippocampal regions of the brain is a major pathological feature of Alzheimer′s disease (AD). Aβ Ser8 phosphorylation is shown to promote Aβ aggregation into oligomeric and fibrillar assemblies and to prevent Aβ proteolytic clearance by certain proteases.

Specificità

Clone 2.F2.19B4, also known as the Jonas antibody, regcognizes a C-terminal epitope present in 10 of the 11 human spliced isoforms reported by UniProt (P05067), with APP305 being the only spliced isoform lacking the targeted epitope. Clone 2.F2.19B4 recognizes full-length APP, the APP C-terminal fragments (CTFs) produced by α- and β-secretase cleavage, and the APP intracellular domain (AICD) generated by γ-secretase cleavage, but not the sAPPα or sAPPβ fragment. Epitope has been mapped to APP770 a.a. 732-751, which is equivalent to APP695 a.a. 657-676 (Van Vickle, G.D., et al. (2007). Biochemistry. 46(36):10317-10327).
