Product Specific Information

The ITEM-4 antibody reacts with human TWEAK Receptor/Fn14 (fibroblast growth factor-inducible 14 kDa protein). Fn14 is distantly related to the TNFR family, containing one cysteine-rich domain in the extracellular region and a TNFR-associated factor binding domain but lacks a death domain (DD) in the cytoplasmic region.

Fn14 plays a role in TWEAK-induced endothelial cell migration, proliferation, and angiogenesis. TWEAK-induced cell death via Fn14 includes both apoptosis and necrosis and can be blocked by an anti-TWEAK antibody (CARL-1). Fn14 is expressed on HUVEC and in some cancer tissues but not on freshly isolated PBMCs. Fn14 mRNA expression has been identified during liver regeneration. ITEM-4 cross-reacts with mouse Fn14, which is constitutively expressed by the Colon 26 cell line.

The ITEM-4 antibody has demonstrated blocking functionality.

Target Information

TWEAK is a member of the TNF family, initially described as a weak inducer of apoptosis. Its receptor, TweakR (Fn14), was identified from a HUVEC cDNA library and belongs to the TNF receptor superfamily. TweakR initiates proliferative signaling by binding to TRAF1, 2, and 3. TweakR mRNA is upregulated during tissue regeneration in the aorta and liver and may play a role in vascular cell migration and angiogenesis.
