Description
AITR Ligand (activation-inducible TNF receptor superfamily member ligand) is also named GITR Ligand (glucocorticoid-induced tumor necrosis factor receptor ligand) and TNFRSF18, regulates T-cell proliferation and survival, and effectuates the interaction between T lymphocytes and endothelial cells. The AITRL gene codes for a type II transmembrane protein comprised of 177 amino acids, including a 28 amino acid cytoplasmic region, a 21 amino acid transmembrane domain and a 128 amino acid extracellular domain. Recombinant human AITRL is a 14.3 kDa protein, containing 126 amino acid residues corresponding to the extracellular domain of AITR Ligand
