site-1 protease

Cleaves sterol regulatory element-binding proteins (SREBPs) and thereby initiates a process by which the active fragments of the SREBPs translocate to the nucleus and activate genes controlling the synthesis and uptake of cholesterol and unsaturated fatty acids into the bloodstream. The enzyme also processes pro-brain-derived neurotrophic factor and undergoes autocatalytic activation in the endoplasmic reticulum through sequential cleavages. The enzyme can also process the unfolded protein response stress factor ATF6 at an Arg-His-Lys-Lys┼ site, and the envelope glycoprotein of the highly infectious Lassa virus and Crimean Congo hemorrhagic fever virus at Arg-Arg-Lys-Lys┼. Belongs in peptidase family S8A.
