Proto-oncogene receptor tyrosine kinase (RTK) ROS or ROS1, is a single-pass type I transmembrane glycoprotein that belongs to the insulin receptor (InsR) subfamily of the tyrosine protein kinase family. ROS1 comprises a 1832-aa large extracellular domain (ECD) with 9 fibronectin type-III motifs, a transmembrane region (TM), and a 465-aa intracellular kinase domain.  ROS1 is an orphan RTK that plays a role in epithelial cell differentiation and regionalization of the proximal epididymal epithelium. ROS1 may activate several downstream signaling pathways related to cell differentiation, proliferation, growth and survival including the PI3 kinase-mTOR signaling pathway.  ROS1 is expressed in brain and its expression is increased in primary gliomas and in a variety of tumor cell lines. A chromosomal aberration involving ROS1 is found in a glioblastoma multiforme sample. A SLC34A2-ROS1 chimeric protein produced in non-small cell lung cancer cells also retains a constitutive kinase activity. A third type of chimeric protein CD74-ROS1 was also identified in those cells.

NCBI Gene ID: 6098

 

Uniprot Entry: P08922

 

Construct Details: Full length human ROS1 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)

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.
