Human CellExp HVEM/TNFRSF14, human recombinant protein
TNFRSF14, ATAR, HVEA, HVEM, LIGHTR, TR2, Tumor necrosis factor receptor superfamily member 14, Herpe
|Calculated MW||This protein is a disulfide-linked homodimeric protein after removal of the signal peptide. The reduced monomer consists of 413 amino. rhHVEM-Fc, fused with the Fc region of human IgG1 at the C-terminus and has a calculated MW of 45.4 kDa expressed. Protein migrates as 50-60 kDa in reduced SDS-PAGE resulting from glycosylation.|
|Other Names||TNFRSF14, ATAR, HVEA, HVEM, LIGHTR, TR2, Tumor necrosis factor receptor superfamily member 14, Herpesvirus entry mediator.|
|Results||Measured by its ability to inhibit TNF-beta-mediated cytotoxicity using L929 Mouse fibrosarcoma cells. The ED50 for this effect is typically 2.5-10 µg/ml in the presence of 1 ng/ml of recombinant human TNF-beta.|
|Application Notes||Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.|
|Storage||-20°C; Lyophilized from 0.22 µm filtered solution in 50 mM tris, 100 mM glycine, pH 7.0. Normally Mannitol or Trehalose is added as protectants before lyophilization.|

Herpesvirus entry mediator (HVEM), also known as TNFRSF14, TR2 (TNF receptor like molecule) and ATAR (another TRAF associated receptor), is a type I membrane protein belonging to the TNF/NGF receptor superfamily. HVEM expression has been detected in peripheral blood T cells, B cells, monocytes and in various tissues enriched in lymphoid cells. The extracellular domain of HVEM has been shown to interact directly with the herpes simplex virus envelope glycoprotein D (gD). Two TNF superfamily ligands, including the secreted TNFβ (lymphotoxin α) and the membrane protein LIGHT (lymphotoxins, exhibits inducible expression, and competes with HSV glycoprotein D for HVEM, a receptor expressed by T lymphocytes), have been shown to be the cellular ligands for HVEM. Besides HVEM, LIGHT can also interact with LTβR, the receptor for lymphotoxin αβ heterotrimer. The role of the HVEM LIGHT /LTβ receptor ligand pair in immune function and herpesvirus pathobiology remains to be elucidated.
