Source

Human DcR3, Fc Tag (TNB-H5255) is expressed from human 293 cells (HEK293). It contains AA Val 30 - His 300 (Accession # O95407-1).

Molecular Characterization

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 56.2 kDa. The protein migrates as 60-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Mass Spectrometry
  • Sequence Coverage

    Human DcR3, Fc Tag(TNB-H5255) was digested with trypsin and characterized by LC-MS/MS peptide mapping, achieving 98.4% sequence coverage (Routinely tested).

  • N-terminal Sequence Analysis

    Val-Ala-Glu-Thr-Pro-Thr-Tyr-Pro-Trp-Arg-Asp-Ala-Glu-Thr-Gly

Background

Tumor necrosis factor receptor superfamily member 6B (TNFRSF6B) is also known as Decoy Receptor 3 (DcR3), Decoy receptor for Fas ligand and M68, which belongs to the tumor necrosis factor receptor superfamily. TNFRSF6 is a soluble protein which contains four TNFR-Cys repeats. Unlike most of the other members of TNFR superfamily, TNFRSF6 is a soluble protein which contains no transmembrane domain. TNFRSF6B acts as a decoy receptor that competes with death receptors for ligand binding. The protein is postulated to play a regulatory role in suppressing FasL- and LIGHT-mediated cell death and T cell activation as well as to induce angiogenesis via neutralization of TL1A.
