Details for messenger / hormone: prostasin

EndoNet ID: ENH00804

To link to the content of EndoNet use the EndoNet ID that is given on the detail pages in the format ENX0000, where X is a place holder for the type of the component (e. g. R for receptor or C for anatomical structure).
As URL for the linking append this ID to the detail page for this type of component.
For an hormone that would be:

If the search pattern is unambigious the user is directed to the corresponding detail page.

Synonyms

  • PRSS8
  • serine protease 8

General information

  • Prostasin has been shown to regulate sodium handling in the kidney. [1]
  • Prostasin, a trypsinlike serine peptidase, is highly expressed in prostate, kidney, and lung epithelia, where it is bound to the cell surface, secreted, or both. [2]
  • Prostasin activates the epithelial sodium channel (ENaC) and suppresses invasion of prostate and breast cancer cells. [2]
  • Serine protease that plays a role in regulation of the amiloride-sensitive epithelial sodium channel, and is overexpressed in ovarian cancer cells. [3]

    • Anatomical structure: kidney

      • We report that endogenous mouse prostasin is glycosylphosphatidylinositol (GPI) anchored to the cell surface and is constitutively secreted from the apical surface of kidney cortical collecting duct cells. [2]
      • We show that prostasin secretion depends on GPI anchor cleavage by endogenous GPI-specific phospholipase D1 (Gpld1). [2]
