H 2 Mab-139 (10 ug/mL; 30 min at 4°C) specifically binds to HER2 on LN229/HER2 glioblastoma cells and the colorectal cancer cell lines Caco-2, HCT-116, HCT-15, HT-29, LS 174T, COLO 201, COLO 205, HCT-8, SW1116, and DLD-1 in flow cytometry assays [1]. H2Mab-139 (10 ug/mL) specifically detects HER2 protein with a molecular weight of approximately 200 kDa in LN229/HER2 glioblastoma cell lysates via Western blotting [1]. H2Mab-139 (10 ug/mL; 1 h at room temperature) specifically stains the cell membrane of HER2-positive human colon cancer tissue sections in immunohistochemical assays [1]. H2Mab-19 (6 ng/mL to 100 ug/mL) maintains high binding affinity for HER2 in HER2-expressing BT-474, HSC-2, and SAS cell lines, with K d values of 2.3 × 10 -8 M, 9.5 × 10 -9 M, and 5.5 × 10 -9 M, respectively [2]. H2Mab-19 (5 h at 37°C) exhibits high CDC activity against BT-474, HSC-2 and SAS cell lines, with cytotoxicity rates of 46%, 51% and 53%, respectively [2]. H2Mab-19 (100 ug per dose; i.p.; on days 1, 7, and 14 after cell implantation) significantly reduces tumor development and tumor weight in BT-474 breast cancer xenografts [2]. H2Mab-19 (100 ug per dose; i.p.; on days 1, 6, and 14 after cell implantation) significantly reduces tumor development and tumor weight in HSC-2 oral cancer xenografts [2]. |

| Фон | Receptor tyrosine-protein kinase erbB-2 (CD340/ERBB2) is a ~137 kDa protein. 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. CD340 is the therapeutic target of trastuzumab (Herceptin) and trastuzumab deruxtecan (Enhertu). |
