Anti-DDR1 Antibody Prodrug, Protease Activated (APE05570)

CAT#: VS-1025-YC178

The Anti-DDR1 Antibody Prodrug, Protease Activated (APE05570) is an antibody prodrug comprised of a recombinant human antibody targeting human DDR1, linked to a masking peptide that conceals the active antigen-binding site via a protease-cleavable linker. The mask peptide is recombinantly attached to the amino terminus of either the light or heavy chain of the antibody, designed to block access to the antigen-binding site and physically prevent the antibody from binding to DDR1 protein. Once the masking peptide is cleaved by matrix metalloproteinases (MMPs), the prodrug is activated, allowing the unmasked monoclonal antibody component to bind to DDR1 effectively. DDR1 (Discoidin Domain Receptor 1) is a receptor tyrosine kinase activated by binding to collagen in the extracellular matrix, which promotes cell survival and invasion. Its overexpression is associated with poor prognosis in a variety of tumors, particularly ovarian and breast cancer.

Target

  • Introduction
  • Receptor tyrosine kinases play a key role in the communication of cells with their microenvironment. These kinases are involved in the regulation of cell growth, differentiation and metabolism. The protein encoded by this gene belongs to a subfamily of tyrosine kinase receptors with homology to Dictyostelium discoideum protein discoidin I in their extracellular domain, and that are activated by various types of collagen. Expression of this protein is restricted to epithelial cells, particularly in the kidney, lung, gastrointestinal tract, and brain. In addition, it has been shown to be significantly overexpressed in several human tumors. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.
