GITR(Glucocorticoid-induced Tumor necrosis factor Receptor), also known as AITR and TNFRSF18, is a 40 kDa transmembrane glycoprotein belonging to the tumor necrosis factor receptor (TNF-R) superfamily. Mature human GITR consists of a 137 amino acid (aa) extracellular domain (ECD) with three tandem TNFR cysteine-rich repeats, a 21 aa transmembrane segment, and a 58 aa cytoplasmic domain. GITR is expressed on CD4+CD25+ regulatory T cells (Treg) as well as on subsets of thymocytes, lymph node cells, and splenocytes. GITR plays a key role in dominant immunological self-tolerance maintained by CD25(+)CD4(+) regulatory T cells.
