| Tissue Specificity | Expressed in placenta. Isoform 1: Predominantly expressed in lung, placenta, pancreas, and prostate. Isoform 3: Expressed in lung, placenta, pancreas, and prostate. Weakly expressed in testis and peripheral blood lymphocytes. |
| Post Translational Modifications | The inactive zymogen is post-translationally modified and then trafficked to the cell surface, whereby it undergoes autocatalytic cleavage resulting in an activated form that is released extracellularly. Phosphorylation is required for localization at the cell surface. Phosphorylation increases following inhibition of protease activity by SPINT2/HAI-2. N-glycosylation of Asn-405 and Asn-445 is required for exit from the endoplasmic reticulum and trafficking to the cell surface. Also required for autocleavage of the zymogen, activation and secretion of the mature protein. |
| Function | Serine protease. Cleaves the proform of PRSS8/prostasin to form the active protein. Cleaves the proform of HGF to form the active protein which promotes MAPK signaling. Promotes the formation of the stratum corneum and subsequently the epidermal barrier in embryos. |
