== Function ==
[https://www.uniprot.org/uniprot/BACE1_HUMAN BACE1_HUMAN] Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of the A-beta peptide sequence, between residues 671 and 672 of APP, leads 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.<ref>PMID:10677483</ref> <ref>PMID:20354142</ref>

== Publication Abstract from PubMed ==
The aspartyl protease beta-secretase, or BACE1, has been demonstrated to be a key factor in the proteolytic formation of Abeta-peptide, a major component of plaques in the brains of Alzheimer's Disease (AD) patients, and inhibition of this enzyme has emerged as a major strategy for pharmacologic intervention in AD. An X-ray based fragment screen of Pfizer's proprietary fragment collection has resulted in the identification of a novel BACE binder featuring spiropyrrolidine framework. Although exhibiting only weak inhibitory activity against the BACE enzyme, the small compound was verified by biophysical and NMR-based methods as a bona fide BACE inhibitor. Subsequent optimization of the lead compound, relying heavily on structure-based drug design and computational prediction of physiochemical properties, resulted in a 1000-fold improvement in potency while maintaining ligand efficiency and properties predictive of good permeability and low P-gp liability.
