Subcellular location

Subcellular Location:
Membrane; Single-pass type I membrane protein. Golgi apparatus. Endoplasmic reticulum. Endosome. Cell surface.

Function

Function:
Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves APP, between residues 690 and 691, leading to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase. It has also been shown that it can cleave APP between residues 671 and 672.
Catalytic Activity:
Broad endopeptidase specificity. Cleaves Glu-Val-Asn-Leu-|-Asp-Ala-Glu-Phe in the Swedish variant of Alzheimer's amyloid precursor protein.
Active Site:
ACT_SITE 110 110; ACT_SITE 303 303
