Verification Image

Western blot analysis was performed on extracts from T47D (lane 1, 15 μg) using ErbB3 / HER3 Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non - fat milk in TBST at 4°C overnight. The primary antibody (1:1000 dilution) and the loading control antibody (beta-Tubulin(HRP), HY-P80955A, 1:5000 dilution) was incubated in 5% non-fat milk in TBST for 1 hour at 37°C. Goat Anti - Rabbit IgG - HRP Secondary Antibody (1:20000 dilution) was then applied for 40 minutes at 37°C.
Western blot analysis was performed on protein extracts (30 μg) from Rat brain (lane 1), Mouse brain (lane 2), and MCF-7 (lane 3) using C-erbB-3/HER3 antibody. Proteins were transferred onto a 0.45 μm PVDF membrane using a wet transfer system for 90 min. The membrane was then blocked with 5% nonfat milk in TBST (HY-K1025) for 1 h at room temperature. Thhe primary antibody (1:500) and loading control antibody GAPDH Antibody (HRP) (HY-P80954A) (1:5000) were diluted in 5% nonfat milk in TBST and incubated with the membrane overnight at 4°C. After washing, the membrane of primary antibody was incubated with HRP-conjugated goat anti-rabbit/mouse IgG secondary antibody (HY-P8001/HY-P8004) (1:5000) diluted in 5% nonfat milk in TBST for 1 h at room temperature. Protein bands were visualized using an Ultra High Sensitivity ECL detection kit (HY-K1005).

Background

Function：Tyrosine-protein kinase that plays an essential role as cell surface receptor for neuregulins. Binds to neuregulin-1 (NRG1) and is activated by it; ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase (PubMed:20682778). May also be activated by CSPG5 (PubMed:15358134). Involved in the regulation of myeloid cell differentiation (PubMed:27416908)

Subcellular Localization：Cell membrane; Single-pass type I membrane protein; Secreted

Expression：
Tissue_specificity:Epithelial tissue and brain

Isoforms & Post-Translational Modification：P21860 has 5 isomers: P21860-1: 148098 Da (predicted); P21860-2: 20136 Da (predicted); P21860-3: 36490 Da (predicted); P21860-4: 141752 Da (predicted); P21860-5: 77426 Da (predicted).
Autophosphorylated (PubMed:20351256). Ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase (PubMed:20682778)

Subunit：Monomer and homodimer. Heterodimer with each of the other ERBB receptors (Potential). Interacts with CSPG5 (PubMed:15358134). Interacts with GRB7 (PubMed:9516479). Interacts with MUC1 (PubMed:12939402). Interacts with MYOC (By similarity). Interacts with isoform 2 of PA2G4 (PubMed:11325528, PubMed:16832058). Found in a ternary complex with NRG1 and ITGAV:ITGB3 or ITGA6:ITGB4 (PubMed:20682778)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
