Furin; Ubiquitous endoprotease within constitutive secretory pathways capable of cleavage at the RX(K/R)R consensus motif. Mediates processing of TGFB1, an essential step in TGF-beta-1 activation. Belongs to the peptidase S8 family. Furin subfamily.

Cathepsin L1 heavy chain; Thiol protease important for the overall degradation of proteins in lysosomes (Probable). Involved in the solubilization of cross-linked TG/thyroglobulin and in the subsequent release of thyroid hormone thyroxine (T4) by limited proteolysis of TG/thyroglobulin in the thyroid follicle lumen. Belongs to the peptidase C1 family.

Processed angiotensin-converting enzyme 2; Carboxypeptidase which converts angiotensin I to angiotensin 1-9, a peptide of unknown function, and angiotensin II to angiotensin 1-7, a vasodilator (By similarity). Also able to hydrolyze apelin-13 and dynorphin-13 with high efficiency (By similarity). By cleavage of angiotensin II, may be an important regulator of heart function. By cleavage of angiotensin II, may also have a protective role in acute lung injury. Plays an important role in amino acid transport by acting as binding partner of amino acid transporter SLC6A19, regulating its tr [...]

Atrial natriuretic peptide-converting enzyme, activated protease fragment; Serine-type endopeptidase involved in atrial natriuretic peptide hormone (NPPA) processing. Converts through proteolytic cleavage the non-functional propeptide NPPA into the active hormone, thereby regulating blood pressure in heart and promoting natriuresis, diuresis and vasodilation. Proteolytic cleavage of pro-NPPA also plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus. Also acts as a regulator of sodium reabsorption in kidney. May also process pro-NPPB [...]

Kunitz-type protease inhibitor 2; Inhibitor of HGF activator.

Serpin B11; Inhibitor of serine proteases. Has moderate inhibitory activity for trypsin-like peptidases, but also some activity with cysteine peptidases, cathepsin L, K, and V, and the serine peptidase, tryptase gamma.

Granzyme G; This enzyme is probably necessary for target cell lysis in cell-mediated immune responses; Belongs to the peptidase S1 family. Granzyme subfamily.

Serine protease 40; May play an important role in the sperm/egg interaction; released during the acrosome reaction; Belongs to the peptidase S1 family.

Hyaluronan-binding protein 2 27 kDa light chain alternate form; Cleaves the alpha-chain at multiple sites and the beta-chain between 'Lys-53' and 'Lys-54' but not the gamma-chain of fibrinogen and therefore does not initiate the formation of the fibrin clot and does not cause the fibrinolysis directly. It does not cleave (activate) prothrombin and plasminogen but converts the inactive single chain urinary plasminogen activator (pro-urokinase) to the active two chain form. Activates coagulation factor VII (By similarity); Belongs to the peptidase S1 family.
