Lua error in Module:Infobox_gene at line 33: attempt to index field 'wikibase' (a nil value). Lymphotoxin beta receptor (LTBR), also known as tumor necrosis factor receptor superfamily member 3 (TNFRSF3), is a cell surface receptor for lymphotoxin involved in apoptosis and cytokine release.[1][2][3] It is a member of the tumor necrosis factor receptor superfamily.
Function
The protein encoded by this gene is a member of the tumor necrosis factor (TNF) family of receptors. It is expressed on the surface of most cell types, including cells of epithelial and myeloid lineages, but not on T and B lymphocytes. The protein specifically binds the lymphotoxin membrane form (a complex of lymphotoxin-alpha and lymphtoxin-beta). The encoded protein and its ligand play a role in the development and organization of lymphoid tissue and transformed cells. Activation of the encoded protein can trigger apoptosis.[1]
Not only does the LTBR help trigger apoptosis, it can lead to the release of the cytokine interleukin 8. Overexpression of LTBR in HEK293 cells increases IL-8 promoter activity and leads to IL-8 release. LTBR is also essential for development and organization of the secondary lymphoid organs and chemokine release.[4]
Structure
The Ramachandran plots show that 64.6% of all residues were in a favored region. This structure was found using X-ray diffraction. The resolution is 3.50 angstroms. The alpha and beta angles are 90 degrees while the gamma angle is 120 degrees.[5]
Interactions
Lymphotoxin beta receptor has been shown to interact with Diablo homolog[6] and TRAF3.[7][8][9]
