Gene Information

human ... ERBB3(2065)

General description

The ErbB3 gene encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. ErbB3 is a membrane-bound protein which has a neuregulin binding domain but not an active kinase domain. It can therefore bind this ligand but cannot convey a signal into the cell via 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.

Specificity

Predicted to cross-react with mouse, rat, and cow.
This antibody recognizes erbB-3/HER-3, Mr 185 kDa. Does not cross-react with erbB-1 (EGFR) and erbB-2/HER-2.

Immunogen

Epitope: a.a. 1295-1323 of human erbB-3
Recombinant rat erbB-3/HER-3 oncoprotein expressed in insect cells and purified by metal chelating chromatography. The epitope maps between amino acid residues 1295-1323 of human erbB-3. Clone 2F12.

Application

Detect erbB-3/HER-3 using this Anti-erbB-3/HER-3 Antibody, clone 2F12 validated for use in IC, IH, IP & WB.
Immunoprecipitation:
4 µg of a previous lot of this antibody immunoprecipitated erbB-3/HER-3 from human MDA and MCF-7 RIPA lysates.

Immunocytochemistry:
10 µg/mL of a previous lot of this antibody gave positive immunostaining for erbB-3/HER-3 in MCF-7cells fixed with 95% ethanol/5% acetic acid.

Immunohistochemistry:
1:50 and 1:100 dilution of a previous lot detected erbB-3/HER-3 membrane staining in human normal and carcinoma breast tissue.
Research Category
Signaling
Research Sub Category
Growth Factors & Receptors

Quality

Routinely evaluated by Western Blot on RIPA lysates of human MCF-7 cells.

Western Blot Analysis:
0.1-2 µg/mL of this lot detected erbB-3/HER-3 in RIPA lysates of human MCF-7 cells. Previous lots have detected erbB-3/HER-3 in MDA RIPA lysates.

Target description

185 kDa

Physical form

Format: Purified
Protein A chromatography

Recurrent human epidermal growth factor receptor 2 (HER2) missense mutations have been reported in human cancers. These mutations occur primarily in the absence of HER2 gene amplification such that most HER2-mutant tumors are classified as "negative" by FISH or immunohistochemistry

Expression of human epidermal growth factor receptor (HER)2 and HER3 have been investigated in small BTC studies using variable scoring systems. HER2 and HER3 overexpression/amplification were explored following internationally agreed guidelines using immunohistochemistry (IHC) and fluorescent in-situ hybridisation (FISH), respectively.
