Preparation and Storage

Background: Lymphotoxin beta R/TNFRSF3

Lymphotoxin beta receptor (LT beta R), also known as TNF RIII and TNF R-related protein (TNF Rrp), was originally identified as a transcribed sequence on human chromosome 12p with homology to the TNF receptor superfamily. In the new TNF nomenclature, LT beta R is referred to as TNFRSF3. Human LT beta R cDNA encodes a 435 amino acid (aa) residue type I membrane protein with a putative 30 aa residue signal peptide, a 193 aa residue extracellular domain and a 171 aa residue cytoplasmic domain. The extracellular domain of LT beta R contains four cysteine-rich motif characteristic of the TNF receptor superfamily. The cytoplasmic region of LT beta R share little sequence similarity with other TNF receptor family members, suggesting that different signaling mechanisms may be utilized. LT beta R is expressed in a variety of tissues including visceral and lymphoid tissues. LT beta R is also expressed by cell lines of monocytic, epithelial, and fibroblastic origins but not by T and B lymphocytes. The human and mouse LT beta R share 76% aa sequence homology. The TNF family ligands that have been shown to bind and activate LT beta R include LIGHT (also a ligand for HVEM) and the heterotrimeric lymphotoxin LT alpha 1/ beta 2 or LT alpha 2/ beta 1. Depending on the cell type, activation of LT beta R has been shown to induce NF kappa B activation, chemokine production, growth arrest, and apoptosis. In vivo, LT beta R has been shown to play a critical role in controlling cellular immune functions and lymphoid organogenesis.
