EGFR is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases (RTK).  Four members of the EGFR family have been identified: EGFR (ERBB1, HER1), HER2 (ERBB2), HER3 (ERBB3) and HER4 (ERBB4).  They typically contain an extracellular ligand binding domain (ECD), a transmembrane domain (TM), and an intracellular kinase domain that can interact with a multitude of signaling molecules and exhibit both ligand-dependent and ligand-independent activity.  The human EGFR has 1210 amino acid (aa), including a 24 aa signal peptide, a 621 aa ECD, and a 23 aa TM segment. It shares 88% aa sequence identity with murine EGFR and 43-44% identity with the ECD of other 3 human EGFR members.  EGFR binds to a subset of the EGF family ligands, including EGF, amphiregulin, TGFα, β-cellulin, epiregulin, HB-EGF, and epigen.  EGFR signaling is initiated by ligand binding, leading to EGFR receptor homo-/hetero-dimerization and autophosphorylation by the intracellular kinase domain and receptor activation.  Subsequently, phosphorylation of cytoplasmic substrates occurs and a signaling cascade is initiated that drives many cellular responses, including changes in gene expression, cytoskeletal rearrangement, anti-apoptosis and increased cell proliferation.  EGFR is known to form heterodimers with the ligand-activated HER3 or HER4.  EGFR is overexpressed in a variety of tumors.  Mutations in EGFR gene are associated with lung cancer.  EGFR is the target for several anti-cancer therapeutics.  The mutations in EGFR can also be a predictive tool for response to the treatment by EGFR kinase inhibitors.  We offer ready-to-transduce lentiviral particles for all the most common EGFR mutations as well as services on any other customized mutations or combinations for your need.

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’-CGGGAAGCAATAGCATGATA-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.
