BACE1 is synthetised in the endoplasmamic reticulum as a precursor, pro BACE1 and it is inactive. This precursor is then maturated in the Golgi apparatus. It undergoes glycosylation of 4 residus : <scene name='56/568015/Asn/1'>Asn(153), Asn(172), Asn(223) and Asn(354) </scene>. This has has a role in the activity. 3 cysteine residues of the cytosolic tail are also palmitoylated , it is has a role in the localization of the mature enzyme. The propeptide domain is clived between Arg 45 and Glu 46 by a proprotein convertase (protease). This clivage is known to increase the activity of the enzyme.
