Data Examples
Detection of Human ErbB3/Her3 by Western Blot.

Western blot shows lysates of MCF‑7 human breast cancer cell line. PVDF Membrane was probed with 1 µg/mL of Goat Anti-Human ErbB3/Her3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF234) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for ErbB3/Her3 at approximately 180kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Cell Proliferation Induced by NRG1‑ beta 1/HRG1‑ beta 1 and Neutralization by Human ErbB3/Her3 Antibody.

Recombinant Human NRG1‑ beta 1/HRG1‑ beta 1 Extracellular Domain (Catalog # 377-HB) stimulates proliferation in the MCF‑7 human breast cancer cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human NRG1‑ beta 1/HRG1‑ beta 1 Extracellular Domain (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human ErbB3/Her3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF234). The ND50 is typically 0.125‑0.5 µg/mL.

Background: ErbB3/Her3

ErbB3, also called Her3 (human epidermal growth factor receptor 3), is a type I membrane glycoprotein that is a member of the ErbB family of tyrosine kinase receptors. ErbB family members serve as receptors for the epidermal growth factor (EGF) family of growth factors. Among ErbB family members, ErbB3 is unique in that it contains a defective kinase domain. ErbB3 is expressed in keratinocytes, melanocytes, skeletal muscle cells, embryonic myoblasts and Schwann cells. Monomeric ErbB3 serves as a low affinity receptor for the heregulins (HRG). ErbB3 heterodimerizes with ErbB2 to form a high affinity receptor complex. In contrast, ErbB3 homodimerization or heterodimerization with ErbB4 forms a low affinity heregulin-binding complex. Because ErbB3 contains a defective kinase domain, the kinase domain of ErbB2 is responsible for initiating the tyrosine phosphorylation signal through the heterodimeric receptor. It has been found that a discrete three amino acid signal in the ErbB3 cytoplasmic domain is critical for transactivation of ErbB2. The cytoplasmic domain of ErbB3 also contains six consensus binding motifs for the SH2 domain of the regulatory p85 subunit of phosphoinositide 3-kinase (PI 3-kinase, PI3K) as well as one proline-rich consensus binding motif for the SH3 domain of p85. Human ErbB3 consists of 1342 amino acids (aa) with a 19 aa signal sequence, a 624 aa extracellular domain, a 21 aa transmembrane region, and a 678 aa cytoplasmic domain. ErbB3 appears to play roles in development, cancer, communication at the neuromuscular junction, and regulation of cell growth and differentiation.
