Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B IP
ErbB2 (also known as Her2 or neu) is a 185kD transmembrane receptor tyrosine kinase from the EGFR family that acts to regulate a variety of biological responses including cell growth, differentiation, and tissue development. Ligand binding to the extracellular domain, or overexpression of the receptor leads to phosphorylation on several tyrosine residues within the cytoplasmic domain, and activation. Overexpression or abnormal activation of ErbB2 has been found in a variety of tumors including brain, breast, lung and skin cancer. Tyrosine 1248 within the cytoplasmic domain of the receptor is an auto-phosphorylation site that allows binding of Shc and activation of the Ras, Raf, ERK1&2 signaling pathway.
