| 别名(Synonyms) | β-分泌酶1；Beta-Secretase 1; Beta-site amyloid precursor protein cleaving enzyme 1; Beta-site APP cleaving enzyme 1 (BACE1); Aspartyl protease 2 (ASP2); Memapsin-2; Membrane-associated aspartic protease 2; APP beta secretase; Aspartic-like protease 56 kDa; HSPC104; BACE-1 |
| 产品简介(Background) | Beyotime’s recombinant active form of human BACE1 (rhBACE1) contain the mature extracellular protease domain (Glu46-Thr457) with a His tag (8X His) at the C-terminus. This protein was expressed in HEK293 cells and purified. The signal peptide (Met1-Gly21), propeptide (The22-Arg45), transmembrane domain (Thr458-Cys478) and cytoplasmic domain (Gln479-Lys501) of human BACE1 was removed during construct. The rhBACE1 consists of 420aa with 2 active sites (Asp93 and Asp289), which has a calculated molecular mass of 46kDa. Due to 4 N-glycosylation sites (Asn153, Asn172, Asn223 and Asn354) of rhBACE1, it migrates as an approximately 66kDa protein in SDS-PAGE gel under reducing conditions. BACE1 is an aspartic protease and an integral membrane protein. It is the peptidase predominantly responsible for cleavage of the amyloid precursor protein beta site to generate the amyloid beta peptide (Aβ) in the brain. Because the Aβ is a major component of amyloid plaques, BACE1 has been implicated in the onset and/or progression of Alzheimer's disease. BACE1 is expressed in a variety of human tissues. It is likely that this peptidase has functions in addition to its hydrolysis of the amyloid precursor protein. The peptidase activity of BACE1 is optimal under mildly acidic conditions (pH3.5-5.5), consistent with its proposed function in an acidic intracellular compartment [1-3]. |
| 产品用途(Applications) | Active human BACE1 is useful in studying enzyme regulation, determining target substrates, screening BACE1 inhibitors or as a positive control in BACE1 activity assays. |
