Function
- cleaves APP between Met671 & Asp672 (APP-770 designation), generating the free NH2 terminus of beta-amyloid (A4), or
- preferentially cuts APP at positions 1 or 11 of A4 sequence[5]
- APP beta-secretase may cleave APP (in part) during late secretory trafficking[8]
- activity may be enhanced by cholesterol or cholesterol esters[7]
- trafficking may be regulated by retromer complex[9]
Compartment
- found mostly in endosomes
Expression
Pathology
- in concert with APP gamma-secretase, generates Abeta
