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. Responsible also for the proteolytic processing of CLTRN in pancreatic beta cells (PubMed:21907142).6 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence.
