General description

The protein named Amyloid beta A4, or ABPP, APP, APPI, Alzheimer disease amyloid protein, Cerebral vascular amyloid peptide, CVAP, PreA4, or Protease nexin II (PN-II) protein and encoded by human gene A4/AD1 is a precursor to 14 peptides some of which are associated with neurological disease such as Alzheimer′s Disease. In pathological conditions Amyloid beta A4 protein is the precursor for the disease associated proteins, Beta amyloid 40, and Beta amyloid 42, major components of plaques in Alzheimer’s Disease. Normally APP plays a role in neuronal development and mediates aspects of axonal transport as well as neurite outgrowth. It is also involved in copper homeostasis/oxidative stress through copper ion reduction in neurons. Amyloid Beta A4 protein is localized to the plasma membrane and Golgi complex until cleaved. Amyloid Beta A4 protein is normally expressed in all fetal tissues and in the adult, frontal cortex expression predominates although there are isoforms widely expressed in non-neuronal cells as well. Normally, amyloid beta A4 is proteolytically processed and the cleavage and secretion of fragments are non-amyloidogenic. However under presenilin/nicastrin mediated processing of the C99 fragment releases beta amyloid proteins that are associated with neurological disease. MABN640 recognizes a specific conformation of residues 2-7 of the amyloid Aß peptide sequence (AEFRHD) found in amyloid fibrils. It does not detectably react with APP, IAPP, a-synuclein or polyQ fibrils A different antibody MABN637, recognizes a specific conformation of residues 3-6 of the amyloid Aß peptide sequence (EFRH) found in amyloid fibrils. It does not recognize pyroglutamyl Aß at residue 3 (1). MABN640 displays a distinct specificity from MABN638 on dot blots of Aß preparations (1). It also reacts with polyQ40 fibrils but not monomers, indicating that it recognizes a generic, sequence independent epitope.

Specificity

MABN640 recognizes a specific conformation of residues 2-7 of the amyloid Aß peptide sequence (AEFRHD) found in amyloid fibrils. It does not detectably react with APP, IAPP, a-synuclein or polyQ fibrils (Hatami et al., manuscript in preparation). This antibody reconizes both Abeta40 and ABeta42.
Other homologies: Broad species cross-reactivity is expected.

Immunogen

Corresponding to the Beta Amyloid Protein 42 (residue 2-7) of human Amyloid beta fibrils.
Epitope: Beta Amyloid Protein 42 (residue 2-7)
