產品描述：

CUSABIO used a DNA fragment (encoding amino acid 20-643 of the human ERBB3) with a C-terminal hFc-tag to generate the recombinant human ERBB3 protein in mammalian cells. This ERBB3 protein was subjected to SDS-PAGE under reducing conditions and presented a molecular mass band of about 115kDa on the gel. Its purity is greater than 95%. The endotoxin content is less than 1.0 EU/ug determined by the LAL method. It has been identified as an active protein through its binding ability with the NRG1 in the functional ELISA. The EC₅₀ is 12.32-15.74 ng/ml. And it is in stock now.

Upon binding to its receptors neuregulins (NRGs), ErBB3 forms heterodimers with other ErBB receptors and triggers phosphorylation cascades that promote crucial cellular functions, including proliferation, differentiation, and survival. ErBB3 also plays an important role in the regulation of cancer progression and therapeutic resistance.

靶點詳情

功能：

Tyrosine-protein kinase that plays an essential role as cell surface receptor for neuregulins. Binds to neuregulin-1 (NRG1) and is activated by it; ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase. May also be activated by CSPG5. Involved in the regulation of myeloid cell differentiation.
