SCCA1 (squamous cell carcinoma antigen 1), also known as SERPINB3 (serpin family B member 3) and Protein T4-A, is a cysteine-type endopeptidase inhibitor of the Ov-serpin subfamily of the serpin family. SCCA1 has protease binding and virus receptor activities. SCCA1 is located in several subcellular components, including cytoplasmic vesicle; cytosol; and extracellular exosome. SCCA1 is involved in several biological processes, including autocrine signaling; paracrine signaling, and regulation of protein metabolic process. SCCA1 is restrictedly expressed in esophagus and its expression is closely related to cellular differentiation in both normal and malignant squamous cells.  SCCA1 acts as a papain-like cysteine protease inhibitor to modulate the host immune response against tumor cells. It also functions as an inhibitor of UV-induced apoptosis. SCCA1 is strongly up-regulated in the upper epidermis of sun-exposed skin and can be secreted in plasma by cancerous cells.

Product Details

 

Gene Symbol: SCCA1; SERPINB3; SCC; T4-A; SSCA1; SCCA-1; HsT1196; SCCA-PD

 

NCBI Gene ID: 6317

 

Uniprot Entry: P29508

 

Construct Details: Full length human SCCA1/SERPINB3 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, 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: 1173 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
