Overview
Product name Active Recombinant Human ErbB-3/HER3 Protein Catalog No. RP00083 Description Active Recombinant Human ErbB-3/HER3 Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Ser20-Thr643) of human ErbB3/Her3 (Accession #NP_001973.2) fused with a 6×His tag at the C-terminus. Bio-Activity Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human ERBB3 at 2 μg/mL (100 μL/well) can bind Recombinant Human NRG1-beta1 with a linear range of 0.128-45.7 ng/mL. Purity > 97% by SDS-PAGE. Endotoxin < 0.1 EU/μg of the protein by LAL method. Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. Species Human Background
This protein is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity. Heterodimerization leads to the activation of pathways which lead to cell proliferation or differentiation. Amplification of this gene and/or overexpression of its protein have been reported in numerous cancers, including prostate, bladder, and breast tumors. Alternate transcriptional splice variants encoding different isoforms have been characterized. One isoform lacks the intermembrane region and is secreted outside the cell. This form acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized.Product information
