Anti-ERBB2 (trastuzumab)-AcLysGly-MMAD ADC (ADC-W-633)

This ADC product is comprised of an engineerd anti-ERBB2 antibody (trastuzumab with LLQGG tag at Fc) conjugated via a AcLysGly linker to MMAD. The MMAD is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, MMAD binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death.

  • Target Entrez Gene ID
  • 2064
  • Overview
  • 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.

 ADC payload drug

  • Name
  • MMAD (monomethyl auristatin D)
  • Description
  • Derived from Auristatin,are water-soluble dolastatin analogs of dolastatin 10. Dolastatin 10 belongs to dolastatin family and it can powerfully bind to tubulin, thus inhibiting polymerization mediated through the binding to the vinca alkaloid binding domain, and causes cell to accumulate in metaphase arrest.
