| Post Translational Modifications | N-Glycosylated. Addition of a bisecting N-acetylglucosamine by MGAT3 blocks lysosomal targeting, further degradation and is required for maintaining stability under stress conditions. Palmitoylation mediates lipid raft localization. Acetylated in the endoplasmic reticulum at Lys-126, Lys-275, Lys-279, Lys-285, Lys-299, Lys-300 and Lys-307. Acetylation by NAT8 and NAT8B is transient and deacetylation probably occurs in the Golgi. Acetylation regulates the maturation, the transport to the plasma membrane, the stability and the expression of the protein. Ubiquitinated at Lys-501, ubiquitination leads to lysosomal degradation. Monoubiquitinated and 'Lys-63'-linked polyubitinated. Deubiquitnated by USP8.inhibits lysosomal degradation. Phosphorylation at Ser-498 is required for interaction with GGA1 and retrograded transport from endosomal compartments to the trans-Golgi network. Non-phosphorylated BACE1 enters a direct recycling route to the cell surface. |
| Function | 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. Cleaves CHL1. |
