Somatostatins are peptide hormones that regulate many biological functions including neurotransmission, cell proliferation, and endocrine signaling as well as inhibiting the release of hormones and other secretory proteins. Somatostatin has two active forms of 14 and 28 amino acids. The biological effects of somatostatins are mediated by a family of 7-transmembrane somatostatin receptors (SSTRs) belonging to the G-protein coupled receptor 1 (GPCR1) superfamily. SSTRs are expressed in a tissue-specific manner. They usually form homodimers and heterodimers with other family members as well as with other GPCRs and receptor tyrosine kinases (RTKs). SSTR4 is a member of the SSTR family with greater affinity for somatostatin-14. SSTR4 is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase. SSTR4 is also functionally coupled to activation of both arachidonate release and mitogen-activated protein (MAP) kinase cascade. SSTR4 mediates anti-proliferative action of somatostatin in tumor cells.

Product Details

 

Gene Symbol: SSTR4; SS-4-R; SS4-R; SS4R

 

NCBI Gene ID: 6754

 

Uniprot Entry: P31391

 

Construct Details: Full length human SSTR4 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: 1167 (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.
