Product name Anti-ERBB2 antibody
Short Description Mouse monoclonal against ERBB2
Description The Her2/Neu (c-erbB-2) proto-oncogene is a transmembrane receptor tyrosine kinase that is clinically indicated in a number of carcinomas. Overexpression of the c-erbB-2 protein has been associated with ductal breast cancer, as well as pulmonary and gastric adenocarcinomas. A correlation between Her2 and p53 has also been documented, as overexpression of both proteins has been associated with early invasion and metastasis in bladder cancer.

Function Protein tyrosine kinase that is part of several cell surface receptor complexes, but that apparently needs a coreceptor for ligand binding, Essential component of a neuregulin-receptor complex, although neuregulins do not interact with it alone, GP30 is a potential ligand for this receptor, Regulates outgrowth and stabilization of peripheral microtubules (MTs), Upon ERBB2 activation, the MEMO1-RHOA-DIAPH1 signaling pathway elicits the phosphorylation and thus the inhibition of GSK3B at cell membrane, This prevents the phosphorylation of APC and CLASP2, allowing its association with the cell membrane, In turn, membrane-bound APC allows the localization of MACF1 to the cell membrane, which is required for microtubule capture and stabilization.
Post-translational Modifications Autophosphorylated, Autophosphorylation occurs in trans, i,e, one subunit of the dimeric receptor phosphorylates tyrosine residues on the other subunit (Probable), Ligand-binding increases phosphorylation on tyrosine residues
Cellular Localization Cell membrane
Tissue Specificity Expressed in a variety of tumor tissues including primary breast tumors and tumors from small bowel, esophagus, kidney and mouth.
