Verification Images

  • Experimental Validation Results for C-erbB-2/HER2 Antibody (YA771)(PBS only)
    Immunocytochemistry analysis of SK-BR-3 cells labeling HER2 with HER2 Antibody (HY-P80658) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with BSA for Immunol Staining for 10 min at room temperature. Cells were then incubated with HER2 Antibody (HY-P80658) at 1/50 dilution in BSA for Immunol Staining at 4 ℃,stay overnight. AF488-conjugated AffiniPure Goat Anti-Mouse IgG H&L(HY-P8005, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background

  • Function

    C-erbB-2/HER2 is a 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; In the nucleus is involved in transcriptional regulation. Associates with the 5'-TCAAATTC-3' sequence in the PTGS2/COX-2 promoter and activates its transcription. Implicated in transcriptional activation of CDKN1A; the function involves STAT3 and SRC. Involved in the transcription of rRNA genes by RNA Pol I and enhances protein synthesis and cell growth

    P04626 has 6 isomers: P04626-1: 137910 Da (predicted); P04626-2: 70917 Da (predicted); P04626-3: 62568 Da (predicted); P04626-4: 136501 Da (predicted); P04626-5: 134856 Da (predicted); P04626-6: 97382 Da (predicted).
    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, PubMed:33497358). Signaling via SEMA4C promotes phosphorylation at Tyr-1248 (PubMed:17554007). Dephosphorylated by PTPN12 (PubMed:27134172)

  • Subunit

    Homodimer (PubMed:21454582). Heterodimer with EGFR, ERBB3 and ERBB4 (PubMed:10358079, PubMed:15093539, PubMed:16978839, PubMed:21190959).
