Recombinant Human ERBB4 Protein (Gln26-Arg649), C-hFc and 6×His-tagged
Product Description
Cat
IMP-9657
Official Symbol
ERBB4
Product Overview
Recombinant human ErbB4/Her4 protein (Gln26-Arg649) with a Human IgG1 (Pro100-Lys330) Fc tag and 6×His tag at C-terminus was expressed in Mouse myeloma cell line.
Description
This gene is a member of the Tyr protein kinase family and the epidermal growth factor receptor subfamily. It encodes a single-pass type I membrane protein with multiple cysteine rich domains, a transmembrane domain, a tyrosine kinase domain, a phosphotidylinositol-3 kinase binding site and a PDZ domain binding motif. The protein binds to and is activated by neuregulins and other factors and induces a variety of cellular responses including mitogenesis and differentiation. Multiple proteolytic events allow for the release of a cytoplasmic fragment and an extracellular fragment. Mutations in this gene have been associated with cancer. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized.
Expression System
Mouse myeloma cell line
Species
Human
Tag
C-hFc and 6×His
Predicted N Terminal
Amino acid sequencing was blocked, suggesting it is consistent with Gln26 as the first N-terminal amino acid
Form
Lyophilized from a 0.2 μm filtered solution in PBS.
Molecular Mass
Predicted Molecular Mass: 97 kDa (monomer)
SDS-PAGE: 122-132 kDa, reducing conditions
Protein length
Gln26-Arg649
Bio-activity
Measured by its ability to inhibit the biological activity of Neuregulin-1-beta 1 on MCF-7 human breast cancer cells. The ED50 for this effect is 1.5-6 μg/mL in the presence of 10 ng/mL of Recombinant Human NRG1-beta 1/HRG1-beta 1 Extracellular Domain.
Endotoxin
<0.01 EU/μg of the protein by the LAL method.
Purity
>90%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Notes
Disulfide-linked homodimer
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution
Reconstitute at 100 μg/mL in sterile PBS.
