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 m\u003c\/p\u003e\u003ch3\u003eAdditional antibody information\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecificity\u003c\/th\u003e\n\u003ctd\u003ePhospho-ErbB-3 (Y1289) Polyclonal Antibody detects endogenous levels of ErbB-3 protein only when phosphorylated at Y1289.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eValidation evidence captions\u003c\/th\u003e\n\u003ctd\u003eWestern Blot analysis of Hela cells using Phospho-ErbB-3 (Y1289) Polyclonal Antibody diluted at 1:1000 cells nucleus extracted by Minute TM Cytoplasmic and Nuclear Fractionation kit (SC-003,Inventbiotech,MN,USA). | Enzyme-Linked Immunosorbent Assay (Phospho-ELISA) for Immunogen Phosphopeptide (Phospho-left) and Non-Phosphopeptide (Phospho-right), using HER3 (Phospho-Tyr1289) Antibody | Immunofluorescence analysis of HeLa cells, using HER3 (Phospho-Tyr1289) Antibody.
