Immunofluorescene (IF)
(MBS9601713 staining MDA-MB-231 by IF/ICC. The sample were fixed with PFA and permeabilized in 0.1% Triton X-100, then blocked in 10% serum for 45 minutes at 25 degree C. The primary antibody was diluted at 1/200 and incubated with the sample for 1 hour at 37 degree C. An Alexa Fluor 594 conjugated goat anti-rabbit IgG (H+L) Ab, diluted at 1/600, was used as the secondary antibody.)

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.
Subunit Structure: Homodimer (PubMed:21454582). Heterodimer with EGFR, ERBB3 and ERBB4 (PubMed:10358079, PubMed:15093539, PubMed:21190959, PubMed:16978839). Part of a complex with EGFR and either PIK3C2A or PIK3C2B. May interact with PIK3C2B when phosphorylated on Tyr-1196 (PubMed:10805725). Interacts with PLXNB1 (PubMed:15210733). Interacts (when phosphorylated on Tyr-1248) with MEMO1 (PubMed:15156151). Interacts with MUC1; the interaction is enhanced by heregulin (HRG) (PubMed:12939402). Interacts (when phosphorylated on Tyr-1139) with GRB7 (via SH2 domain) (PubMed:12975581). Interacts (when phosphorylated on Tyr-1248) with ERBIN (PubMed:12444095). Interacts with KPNB1, RANBP2, EEA1, CRM1 and CLTC (PubMed:16314522). Interacts with PTK6 (PubMed:18719096). Interacts with RPA194 and ACTB (PubMed:21555369). Interacts with PRKCABP, SRC and MYOC (By similarity). Interacts (preferentially with the tyrosine phosphorylated form) with CPNE3; this interaction occurs at the cell membrane and is increased in a growth factor heregulin-dependent manner (PubMed:20010870). Interacts with HSP90AA1 and HSP90AB1 in an ATP-dependent manner; the interaction suppresses ERBB2 kinase activity (PubMed:26517842).
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 (PubMed:27134172). Signaling via SEMA4C promotes phosphorylation at Tyr-1248 (PubMed:17554007). Dephosphorylated by PTPN12 (PubMed:27134172).
Similarity: Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily.

NCBI Description
This gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized. [provided by RefSeq, Jul 2008]

Product Notes
The HER2 erbb2 (Catalog #AAA9601713) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The HER2 Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's HER2 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunofluorescence (IF), Immunocytochemistry (ICC), ELISA (EIA). WB: 1:500-1:2000 IF/ICC: 1:100-1:500. Researchers should empirically determine the suitability of the HER2 erbb2 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "HER2, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
