摘要
HER2 antibody recognizes HER2 protein, also known as proto-oncogene Neu or ERBB2 (predicted molecular weight of 138 kDa). HER2 is a member of the human epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. It shares 50% sequence identity with EGFR protein, but involves different signaling pathways. HER2 can heterodimerize with EGFR protein or homodimerize when it is present in high concentrations.

功能与背景
This gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized. [provided by RefSeq]

GTX100509 WB Image
Wild-type (WT) and Her2 / ErbB2 knockout (KO) HeLa cell extracts (30 μg) were separated by 5% SDS-PAGE, and the membrane was blotted with Her2 / ErbB2 antibody (GTX100509) diluted at 1:5000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody, and the signal was developed with Trident femto Western HRP Substrate.
