Anti-STEAP-1 (clone 120)-Mc-MMAF ADC (ADC-W-146)

This ADC product is comprised of an anti-STEAP1 monoclonal antibody (clone 120) conjugated via a Mc linker to MMAF. The MMAF is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, MMAF binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death.
  • Antibody clone #
  • 120

 ADC Target

  • Name
  • STEAP
  • Alternative Names
  • STEAP1; six transmembrane epithelial antigen of the prostate 1; STEAP; PRSS24; metalloreductase STEAP1; six-transmembrane epithelial antigen of prostate 1;
  • Target Entrez Gene ID
  • 26872
  • Overview
  • This gene is predominantly expressed in prostate tissue, and is found to be upregulated in multiple cancer cell lines. The gene product is predicted to be a six-transmembrane protein, and was shown to be a cell surface antigen significantly expressed at cell-cell junctions.

 ADC Linker

  • Name
  • Mc (maleimidocaproyl)
  • Description
  • Noncleavable linkers, is considered noncleavable-meaning linker cleavage, and payload release does not depend on the differential properties between the plasma and some cytoplasmic compartments. Instead, the release of the cytotoxic drug is postulated to occur after internalization of the ADC via antigen-mediated endocytosis and delivery to lysosomal compartment, where the antibody is degraded to the level of amino acids through intracellular proteolytic degradation.

 ADC payload drug

  • Name
  • MMAF (Monomethyl auristatin F)
  • 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.
