background:
TMPRSS4 is a member of the peptidase S1 family and contains 1 LDL receptor class A domain, 1 peptidase S1 domain and 1 SRCR domain. It is a probable membrane protease capable of activating ENaC and may process sodium channels in endothelial cells. TMPRSS4 is overexpressed in thyroid neoplasms, and splice variants in TMPRSS4 are thought to be linked with different cancers. Three named isoforms are produced by alternative splicing.
Function:
Probable protease. Seems to be capable of activating ENaC.
Subcellular Location:
Membrane; Single-pass type II membrane protein (Potential).
Tissue Specificity:
High levels in pancreatic, gastric, colorectal and ampullary cancer. Very weak expression in normal gastrointestinal and urogenital tract.
Similarity:
Belongs to the peptidase S1 family.
Contains 1 LDL-receptor class A domain.
Contains 1 peptidase S1 domain.
Contains 1 SRCR domain.
