ST14 (suppressor of tumorigenicity 14 protein) is an epithelial-derived, 1 pass type II transmembrane serine protease belonging to the peptidase S1 family. ST14 contains 2 CUB, 4 LDL-receptor class A, 1 peptidase S1 and 1 SEA domains in the extracellular region. ST14 may form a complex with the Kunitz-type serine protease inhibitor, HAI-1, and is found to be activated by sphingosine 1-phosphate. This protease has been shown to cleave and activate hepatocyte growth factor/scattering factor, and urokinase plasminogen activator, which suggest the function of this protease as an epithelial membrane activator for other proteases and latent growth factors. ST14 degrades extracellular matrix and exhibits trypsin-like activity as defined by cleavage of synthetic substrates with Arg or Lys as the P1 site. ST14 mat be involved in the terminal differentiation of keratinocytes through prostasin (PRSS8) activation and filaggrin (FLG) processing.  The expression of ST14 has been associated with breast, colon, prostate, and ovarian tumors, which implicates its role in cancer invasion, and metastasis.  A mutation in ST14 is associated with autosomal recessive ichthyosis with hypotrichosis.

NCBI Gene ID: 6768

 

Uniprot Entry: Q9Y5Y6

 

Construct Details: Full length human ST14 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 2568 (bp)
