Human
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the sequence of mouse MBTPS2. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Membrane-bound transcription factor protease site 2 (MBTPS2), also known as site-2 protease (S2P), is a zinc metalloprotease in the Golgi membrane (1,2,3). It regulates cholesterol metabolism (1,2) and unfolded protein response (UPR) (3,4). When cells are deprived of cholesterol, sterol regulatory element-binding proteins (SREBPs) move from the endoplasmic reticulum (ER) to the Golgi apparatus and are cleaved by site-1 protease (S1P) (5,6) and site-2 protease (1,6) sequentially to release the active amino-terminal domains. These amino-terminal domains of SREBPs then translocate into the nucleus to induce expression of genes for cholesterol biosynthesis. During UPR, activating transcription factor 6 (ATF6) transports from ER to Golgi apparatus and is cleaved by S1P and S2P to release a cytosolic fragment. This cytosolic fragment relocates to the nucleus and activates the UPR gene expression (7).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
