Human OX40L/TNFSF4/GP34/CD252/TXGP1/CD134L Protein, ECD (Extracellular Domain), Fc-fusion, Recombinant

Description

OX40L (OX40 ligand), also known as TNFSF4, gp34 and CD252, is a cytokine that belongs to the tumor necrosis factor (TNF) superfamily. OX40L is a single-pass type II transmebrane glycoprotein consisting of a 23 amino acid (aa) cytoplasmic domain, a 27-aa transmembrane domain (TM) and a 133 aa extracellular domain (ECD). OX40L is expressed on the surface of activated B cells, T cells, dendritic cells and endothelial cells. Similarly to other TNF superfamily members, membrane-bound OX40L exists as a homotrimer. OX40L binds to OX40/CD134, a member of the TNF receptor superfamily that is expressed predominantly on activated CD4+ T cells. OX40 Ligand is one of the co¬stimulatory molecules in the regulation of T-cell-mediated immunity that includes B7, CD40L, CD30L, CD27L/CD70 and 4-1BBL. OX40L functions in T cell antigen-presenting cell (APC) interactions and mediates adhesion of activated T cells to endothelial cells. Polymorphisms in the OX40L gene have been associated with Sjogren's syndrome and systemic lupus erythematosus.  The interaction of OX40L:OX40 is also involved in the pathogenesis of carotid artery disease and cancer.  Engagement of OX40 on activated T cells in situ in tumors has been shown to augment immune responses and subsequent tumor regression.
