Relevance
S1P (also known as MBTPS1,SKI1), was first discovered as one of two enzymes that cleave the sterol regulatory binding proteins (SREBPs), in the case of S1P at “site-1,” a hydrophillic loop extending into the lumen of the ER. The MBTPS1 domain structure contains a signal sequence followed by a propeptide domain, a catalytic domain, a transmembrane domain and a cytoplasmic domain. -

Secondary
Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 118 kDa
Exposure time: 16 minutes
The 148 kDa zymogen is processed progressively into two membrane-bound 120 and 106 kDa forms in the endoplasmic reticulum, and late into a secreted 98 kDa form. The propeptide is autocatalytically removed through an intramolecular cleavage after Leu-186. Further cleavage generates 14, 10, and 8 kDa intermediates.
