MA5-15536 targets ERBB3 in IF and WB applications and shows reactivity with Human samples.
The MA5-15536 immunogen is purified recombinant extracellular fragment of human ERBB3 (aa22-369) fused with hIgGFc tag expressed in HEK293 cells.
MA5-15536 detects ERBB3 which has a predicted molecular weight of approximately 148kDa.
This gene encodes a member of the epidermal growth factor receptor 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.
