| Tissue Specificity | Expressed in polymorphonuclear leukocytes (at protein level). Expressed in neutrophils (at protein level). Expressed in differentiating neutrophils. |
| Function | Serine protease that degrades elastin, fibronectin, laminin, vitronectin, and collagen types I, III, and IV (in vitro). By cleaving and activating receptor F2RL1/PAR-2, enhances endothelial cell barrier function and thus vascular integrity during neutrophil transendothelial migration. Plays a role in neutrophil transendothelial migration, probably when associated with CD177. Triggers inflammatory processes in neutrophils by interacting with ADGRG3 upstream of F2RL1/PAR2 activation. |
