MBTPS2 (human)

Overview
MBTPS2 Intramembrane proteolysis of sterol-regulatory element- binding proteins (SREBPs) within the first transmembrane segment thereby releasing the N-terminal segment with a portion of the transmembrane segment attached. Site-2 cleavage comes after site-1 cleavage which takes place in the lumenal loop. Expressed in heart, brain, placenta, lung, liver, muscle, kidney and pancreas. Belongs to the peptidase M50A family. Note: This description may include information from UniProtKB.
