Beta-secretase 2 (BACE2)

Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves APP, involving residues 690 and 691, causing the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C- terminal fragment that's later released by gamma-secretase.

Additionally, it has been shown that it may cleave APP between residues 671 and 672. Responsible also for the proteolytic processing of CLTRN in pancreatic beta cells (PubMed:21907142).
