Comments

Comment Type Description
Catalytic Activity Processes precursors containing basic and hydrophobic/aliphatic residues at P4 and P2, respectively, with a relatively relaxed acceptance of amino acids at P1 and P3.
Cofactor Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
Enzyme Regulation Inhibited by divalent copper and zinc ions, but not by nickel or cobalt. Inhibited by its prosegment, but not smaller fragments thereof (By similarity). {ECO:0000250}.
Function Serine protease that catalyzes the first step in the proteolytic activation of the sterol regulatory element-binding proteins (SREBPs). Other known substrates are BDNF, GNPTAB and ATF6. Cleaves after hydrophobic or small residues, provided that Arg or Lys is in position P4. Cleaves known substrates after Arg- Ser-Val-Leu (SERBP-2), Arg-His-Leu-Leu (ATF6), Arg-Gly-Leu-Thr (BDNF) and its own propeptide after Arg-Arg-Leu-Leu. Mediates the protein cleavage of GNPTAB into subunit alpha and beta, thereby participating in biogenesis of lysosomes (By similarity). {ECO:0000250}.
Ptm 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 (By similarity). {ECO:0000250}.
Similarity Belongs to the peptidase S8 family. {ECO:0000305}.
Similarity Contains 1 peptidase S8 domain. {ECO:0000305}.
Subcellular Location Endoplasmic reticulum membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Golgi apparatus membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Note=May sort to other organelles, including lysosomal and/or endosomal compartments. {ECO:0000250}.
