Background | Receptor tyrosine-protein kinase erbB-3, also known as HER3 (human epidermal growth factor receptor 3), is a membrane bound protein that in humans is encoded by the ERBB3 gene.ErbB3 is a member of the epidermal growth factor receptor (EGFR/ERBB) family of receptor tyrosine kinases. The kinase-impaired ErbB3 is known to form active heterodimers with other members of the ErbB family, most notably the ligand binding-impaired ErbB2.ERBB3 (Erb-B2 Receptor Tyrosine Kinase 3) is a Protein Coding gene. Diseases associated with ERBB3 include Lethal Congenital Contracture Syndrome 2 and Erythroleukemia, Familial. Among its related pathways are PI3K/AKT activation and RET signaling. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and transferase activity, transferring phosphorus-containing groups. An important paralog of this gene is ERBB4. |
Description | A DNA sequence encoding the extracellular domain (Met 1-Thr 643) of human ErbB3 (NP_001973.2) precursor was expressed, with a C-terminal His tag. |
Source | HEK293 |
Predicted N Terminal | Ser 20 |
AA Sequence | Met 1-Thr 643 |
Molecular Weight | The recombinant human ErbB3 protein consists of 635 amino acids after the removal of signal peptide and has a calculated molecular mass of 70.2 kDa. As a result of glycosylation, the recombinant ErbB3 migrates as an approximately 100-110 kDa band in SDS-PAGE under reducing conditions. |
Purity | >95% as determined by SDS-PAGE |
Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
Bioactivity | 1. Measured by its binding ability in a functional ELISA.2. Immobilized human ErbB3 at 2 ug/mL (100 ul/well) can bind human NRG1 (isoform Beta1), The EC50 of human NRG1 (isoform Beta1) is 0.43 ug/mL. |
