Human Lymphotoxin beta receptor (LTbR, TNFSF3) is a member of the TNF receptor superfamily with similarilty to CD120a(TNFR1) and CD120b(TNFR2).  It is a expressed mainly on non lymphoid tissues(1) and appears to have an important role in secondary lymphoid organ development(5). Suppression of LTbR signaling can alleviate autoimmunity(2) or exasperate mycobacterial infection(6).  Its  ligands include Ltab 2 and LIGHT.  In mice, LTbR signaling is important for development and function of HEV(2), Dendritic cells(3), and Mast cells(4).

Molecular Structure: A soluble fusion protein consisting of 10 residual amino acids from murine CD8 alpha leader sequence (KPQAPELRGS), followed by the mature extracellular (192aa) domain of human LTbR (SQPQAVP….PLEPLPP) fused to (233aa) murine IgG2a Fc (EPRGPTI….FSRTPGK).  Predicted non glycosylated molecular weight of  48.9 kd.

Transfectant Cell Line: CHO

Functional Application: Recombinant human LTbR-muIg fusion protein binds to recombinant human LIGHT in EIA.
