The Phospho-ErbB3/HER3-Y1328 Antibody (CABP0277) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, raised in rabbits, is highly reactive with human samples and has been validated for use in Western blot applications.ERBB3 (epidermal growth factor receptor 3) is a key player in cell growth and differentiation, functioning as a receptor for neuregulins. Phosphorylation of ERBB3 at tyrosine 1328 is known to activate downstream signaling pathways involved in cell proliferation and survival.This antibody specifically targets the phosphorylated form of ERBB3 at tyrosine 1328, allowing for its detection and analysis in various cell types.
This antibody is validated for use in WB, IF/ICC, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

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