Product Description | Recombinant Biotinylated Human EGFR/HER1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Leu25-Ser645. |
Product Background |
The epidermal growth factor receptor is a transmembrane protein that is a receptor for members of the epidermal growth factor family of extracellular protein ligands. The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR, HER2/neu, Her 3 and Her 4. Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. |
