In molecular biology, the<unk>  <unk>  is a type of protein that specifically cleaves parts of other proteins. It is an intramembrane aspartyl protease with the conserved active site motifs 'YD' and 'GxGD' in adjacent transmembrane domains (TMDs). Its sequences is highly conserved in different vertebrate species.<unk>  cleaves remnant<unk><unk> s left behind in membrane by the action of<unk> <unk> se and also plays key roles in immune surveillance and the maturation of certain viral proteins.
