General description

Presenilin 1& 2 (PS1 and PS2) are highly homologous proteins (approx. 43-52 kD) with eight transmembrane domains. In the brain, PS1 and PS2 are expressed primarily in neurons and localized mainly in cell bodies, axons and dendrites. In non-neuronal cells, PS1 and PS2 are localized to the nuclear membrane, endoplasmic reticulum and Golgi. Presenilin 1 is located on chromosome 14.

Specificity

Specific for presenilin 1 (not found in presenilin 2) and is identical in mouse, rat, and Xenopus. By immunoblotting, the antibody reacts with presenilin 1 (PS1, S182) and with the PS1 cleavage product.

Immunogen

synthetic peptide corresponding to the C-terminal of human presenilin-1 (amino acids 450-467 with N-terminally added lysine) conjugated to KLH.

Application

Anti-Presenilin-1 (S182) antibody produced in rabbit has been used in:
  • immunostaining
  • immunofluorescence detection
  • immunohistochemistry
  • immunoblotting

Biochem/physiol Actions

The biological functions of the presenilin′s are yet unknown, but they are thought to be involved in protein trafficking. Mutations in the presenilin 1 (PS1) gene (>30 known pathogenic mutations) have been found in about half of the early-onset familial Alzheimer′s disease (FAD), while only two pathogenic mutations have been found in PS2.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Although the beneficial responses induced in the central nervous system by early-initiated exercise have been broadly investigated, the effects of a chronic and moderate lately-initiated exercise on biochemical hallmarks of very early brain senescence have not been extensively studied. We...

The cleavage of the transmembrane amyloid precursor protein (APP) by beta-secretase leaves the C-terminal fragment of APP, C99, anchored in the plasma membrane. C99 is subsequently processed by gamma-secretase, an unusual aspartyl protease activity largely dependent on presenilin (PS), generating...
