LTK receptor yrosine-protein kinase (RTK), is a single-pass type I transmembrane glycoprotein that belongs to the insulin receptor (InsR) subfamily of the tyrosine protein kinase family. LTK comprises a 408-aa large extracellular domain (ECD), a transmembrane region (TM), and a 415-aa intracellular kinase domain.  LTK is expressed in non-hematopoietic cell lines and T- and B-cell lines.  The exact function of LTK is not known. Studies with chimeric proteins (replacing its extracellular region with that of several known growth factor receptors, such as EGFR and CSFIR) demonstrate its ability to promote growth and specifically neurite outgrowth, and cell survival. Signaling appears to involve the PI3 kinase pathway. LTK may be involved in regulation of the secretory pathway involving endoplasmic reticulum (ER) export sites (ERESs) and ER to Golgi transport.

Product Details

 

Gene Symbol: LTK; TYK1

 

NCBI Gene ID: 4058

 

Uniprot Entry: P29376

 

Construct Details: Full length human LTK gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without an antibiotic 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: 2595 (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.
