Immunofluorescent analysis of Phospho-ERBB2 Tyr1005 showing staining in the membrane and cytoplasm of MCF-7 cells. MCF-7 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min) and probed with a Phospho-ERBB2 Tyr1005 polyclonal antibody (Product # PA5-35310) at a dilution of 1:100 for 2 hours at room temperature, followed by detection using a fluorescent conjugated secondary antibody (green) (1:1000, 1h). Nuclei were stained with Hoechst 33342 (blue) (10 ug/ml, 5 min).

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.
