Target: BACE1 (Beta-secretase 1 (BACE1))

Protein Type: Recombinant

Biological Activity: Active

Origin: Human

Source: HEK-293 Cells

Purity: > 95 % as determined by reducing SDS-PAGE.

Product Details

Purpose: Recombinant Human BACE1/ASP2 Protein (Active)

Sequence: Met 1-Thr 457

Characteristics: The mature form of human BACE1 (NP_036236.1) extracellular domain (Met1-Thr 457) with a quinary-aa peptide (DDDDK) at the C-terminus was expressed and purified.

Endotoxin Level: < 1.0 EU per μg as determined by the LAL method.

Biological Activity Comment: Measured by its ability to cleave a fluorescent peptide substrate Mca-Ser-Glu-Val-Asn-Leu-Asp-Ala-Glu-Phe-Arg-Lys(Dpn)-Arg-Arg-NH2 (Catalog# ES004, R&D Systems). Cleavage of ES004 can be measured using excitation and emission wavelength of 320 and 405 nm, respectively. The specific activity is >3.5 pmoles/min/μg.

Alternative Name: BACE1

Background:

Background: Beta-site APP-cleaving enzyme 1 (BACE1) is an aspartic-acid protease important in the formation of myelin sheaths in peripheral nerve cells. In the brain, This protein is expressed highly in the substantia nigra, locus coruleus and medulla oblongata. Strong BACE1 expression has also been described in pancreatic tissue. BACE1 has a pivotal role in the pathogenesis of Alzheimer's disease. In Alzheimer's disease patients, BACE1 levels were elevated although mRNA levels were not changed. It has been found that BACE1 gene expression is controlled by a TATA-less promoter. The translational repression as a new mechanism controlling its expression. And the low concentrations of Ca(2+) (microM range) significantly increased the proteolytic activity of BACE1. Furthermore, BACE1 protein is ubiquitinated, and the degradation of BACE1 proteins and amyloid precursor protein processing are regulated by the ubiquitin-proteasome pathway. It has also been identified as the rate limiting enzyme for amyloid-beta-peptide (Abeta) production.
