Goat anti Human Erb3 antibody is generated against a peptide located within the C-terminal region and is expected to recognize membrane bound isoforms 1,4 and 5 but not the short isoforms 2 and 3. ErbB3 is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases and has neuregulin binding avtivity (Carraway et al. 1994). Heterodimerization of ErbB3 with other EGFR family members leads to cell proliferation and/or differentiation (Carraway and Cantley 1994).
Amplification of this gene and/or over expression of its protein has been reported in numerous cancers, including prostate, bladder, and breast tumors. In breast cancer it has been shown to dimerize with ErbB2 to drive tumor cell proliferation (Alimandi et al. 1995).
Goat anti Human ErbB3 antibody recognizes human ErbB3 as a 185 kDa band in a number of human cell line lysates tested. It also demonstrates cross reacts with rodent cell lines.
