Anti-PDGFB Antibody Prodrug, Protease Activated (VS-1025-YC106)

CAT#: VS-1025-YC106

The Anti-PDGFB Antibody Prodrug, Protease Activated (VS-1025-YC106) is an antibody prodrug comprised of a recombinant human antibody targeting human PDGFB, 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 PDGFB protein. Once the masking peptide is cleaved by matrix metalloproteinases (MMPs), the prodrug is activated, allowing the unmasked monoclonal antibody component to bind to PDGFB effectively. PDGFB (Platelet-Derived Growth Factor B) is a growth factor that acts as a potent stimulator of the tumor microenvironment, specifically by promoting the proliferation of pericytes and fibroblasts. Secreted by tumor cells, PDGFB recruits and activates these stromal components, leading to the formation of a dense, supportive connective tissue and contributing to the metastatic process.

Target

  • Introduction
  • This gene encodes a member of the protein family comprised of both platelet-derived growth factors (PDGF) and vascular endothelial growth factors (VEGF). The encoded preproprotein is proteolytically processed to generate platelet-derived growth factor subunit B, which can homodimerize, or alternatively, heterodimerize with the related platelet-derived growth factor subunit A. These proteins bind and activate PDGF receptor tyrosine kinases, which play a role in a wide range of developmental processes. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 17, at sites where this gene and that for collagen type 1, alpha 1 are located, are associated with dermatofibrosarcoma protuberans, a rare skin tumor. Alternative splicing results in multiple transcript variants.
