Anti-Kel Antibody Prodrug, Protease Activated (MIMA-8)

CAT#: VS-1025-YC125

The Anti-Kel Antibody Prodrug, Protease Activated (MIMA-8) is an antibody prodrug comprised of a recombinant human antibody targeting human Kell protein, 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 Kel protein. Once the masking peptide is cleaved by matrix metalloproteinases (MMPs), the prodrug is activated, allowing the unmasked monoclonal antibody component to bind to Kel effectively. The Kell protein is a complex protein found on the surface of red blood cells. While not directly oncogenic, its gene is occasionally involved in chromosomal translocations that result in the fusion of the KEL gene with a tyrosine kinase gene. This fusion creates a constitutively active oncogenic kinase that can drive a rare subset of hematological malignancies.

Target

  • Introduction
  • This gene encodes a type II transmembrane glycoprotein that is the highly polymorphic Kell blood group antigen. The Kell glycoprotein links via a single disulfide bond to the XK membrane protein that carries the Kx antigen. The encoded protein contains sequence and structural similarity to members of the neprilysin (M13) family of zinc endopeptidases.
  • Alternative Names
  • Kell Blood Group, Metallo-Endopeptidase; Truncated Kell Blood Group Glycoprotein; Kell Blood Group, Metalloendopeptidase; Kell Blood Group Glycoprotein; Kell Blood Group Antigen; Kell Glycoprotein;
