Anti-KDR Antibody Prodrug, Protease Activated (VS-1025-YC53)

CAT#: VS-1025-YC53

The Anti-KDR Antibody Prodrug, Protease Activated (VS-1025-YC53) is an antibody prodrug comprised of a recombinant rabbit antibody targeting human KDR, 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 KDR protein. Once the masking peptide is cleaved by matrix metalloproteinases (MMPs), the prodrug is activated, allowing the unmasked monoclonal antibody component to bind to KDR effectively. KDR (Kinase insert Domain Receptor), also known as VEGFR2, is the primary receptor for VEGF and the most important mediator of angiogenesis (new blood vessel formation) in tumors. Upon activation by VEGF, KDR signaling drives the proliferation and migration of endothelial cells, forming the blood supply necessary for a tumor to grow beyond a tiny mass. Therapies targeting KDR are a major strategy to starve tumors.

Target

  • Introduction
  • Vascular endothelial growth factor (VEGF) is a major growth factor for endothelial cells. This gene encodes one of the two receptors of the VEGF. This receptor, known as kinase insert domain receptor, is a type III receptor tyrosine kinase. It functions as the main mediator of VEGF-induced endothelial proliferation, survival, migration, tubular morphogenesis and sprouting. The signalling and trafficking of this receptor are regulated by multiple factors, including Rab GTPase, P2Y purine nucleotide receptor, integrin alphaVbeta3, T-cell protein tyrosine phosphatase, etc. Mutations of this gene are implicated in infantile capillary hemangiomas.
  • Alternative Names
  • FLK1; CD309; VEGFR; VEGFR2
