Background
| Function | FUNCTION: Plasma membrane-anchored serine protease that directly induces processing of pro-uPA/PLAU into the active form through proteolytic activity (PubMed:24434139). Seems to be capable of activating ENaC (By similarity). {ECO:0000250|UniProtKB:Q8VCA5, ECO:0000269|PubMed:24434139}.; FUNCTION: (Microbial infection) In gut epithelial cells, facilitates human coronavirus SARS-CoV-2 infection through, at least, the cleavage of coronavirus spike glycoproteins which activates the glycoprotein for host cell entry. {ECO:0000269|PubMed:32404436}. |
| Pathway | |
| Protein Families | Peptidase S1 family |
| Tissue Specificity | High levels in pancreatic, gastric, colorectal and ampullary cancer. Very weak expression in normal gastrointestinal and urogenital tract (PubMed:10825129). Coexpressed with ACE2 within mature enterocytes (PubMed:32404436). {ECO:0000269|PubMed:10825129, ECO:0000269|PubMed:32404436}. |
