The human pregnancy-specific glycoproteins (PSGs) are a family of proteins that are synthesized in large amounts by placental trophoblasts and released into the maternal circulation during pregnancy.  The PSGs form a subgroup of the carcinoembryonic antigen (CEA) gene family, which belongs to the immunoglobulin superfamily (IgSF).  Members of the CEA family consist of a single N domain, with structural similarity to the Ig variable (IgV) domains, followed by a variable number of Ig constant-like 1 (IgC1) and/or 2 (IgC2) domains.  Most PSGs have an arg-gly-asp (RGD) motif, which has been shown to function as an adhesion recognition signal for several integrins, in the N-terminal domain.  PSG3 (Pregnancy-specific beta-1-glycoprotein 3) is a secreted glycoprotein of the CEA family. Human PSG3 contains 1 IgV domain (IgV) and 3 C2-type (IgC2) domains with multiple sites for glycosylation. PSG3 is is a product of the syncytiotrophoblast.  The human placenta is a multihormonal endocrine organ that produces hormones, enzymes, and other molecules that support fetal survival and development.

Product Details

 

Gene Symbol: PSG3; PSBG3; PSBG-3; PS-beta-G3; SG5

 

NCBI Gene ID: 5671

 

Uniprot Entry: P16557

 

Construct Details: Full length human PSG3 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: 1287 (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.
