CD127, also known as IL7RA/IL7R (Interleukin-7 receptor subunit alpha), is a single pass, type I transmembrane glycoprotein of the type I cytokine receptor family, type 4 subfamily.  CD127 consists of a extracellular region with 1 fibronectin type III (FN3) domains and a juxtamembrane WSXWS motif, a transmembrane domain, and a cytoplasmic tail with the box 1 motif.  The WSXWS motif is necessary for proper protein folding and efficient intracellular transport and cell-surface receptor binding, while the box 1 motif is required for JAK interaction/activation. CD127 is a component of the receptor complex for interleukin-7 and thymic stromal lymphopoietin (TSLP). The IL7 receptor complex is a heterodimer of CD127/IL7R and the common subunit CD132/IL2RG shared by the receptors for interleukins 2, 4, 7, 9, and 15.. The TSLP receptor complex is a heterodimer of TSLPR/CRLF2 and CD127/IL7R. CD127 has been shown to play a critical role in V(D)J recombination during lymphocyte development. Defects in the CD127 gene may be associated with severe combined immunodeficiency (SCID) and multiple sclerosis 3 (MS3).

Product Details

 

Gene Symbol: IL7R; ILRA; CD127; IL7RA; CDW127; IL-7R-alpha

 

NCBI Gene ID: 3575

 

Uniprot Entry: P16871

 

Construct Details: Full length human CD127/IL7R 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: 1380 (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.
