[https://www.uniprot.org/uniprot/TNF18_MOUSE TNF18_MOUSE] Cytokine that binds to TNFRSF18/AITR/GITR (PubMed:14521928, PubMed:14647196). Regulates T-cell responses (PubMed:14647196). Can function as costimulator and lower the threshold for T-cell activation and T-cell proliferation (PubMed:14608036, PubMed:15128759). Important for interactions between activated T-lymphocytes and endothelial cells. Mediates activation of NF-kappa-B (PubMed:14521928, PubMed:14647196, PubMed:18178614). Triggers increased phosphorylation of STAT1 and up-regulates expression of VCAM1 and ICAM1 (By similarity). Promotes leukocyte adhesion to endothelial cells (PubMed:23892569). Regulates migration of monocytes from the splenic reservoir to sites of inflammation (PubMed:24107315).[UniProtKB:Q9UNG2]<ref>PMID:14521928</ref> <ref>PMID:14608036</ref> <ref>PMID:14647196</ref> <ref>PMID:15128759</ref> <ref>PMID:18178614</ref> <ref>PMID:23892569</ref> <ref>PMID:24107315</ref>

== Publication Abstract from PubMed ==
 +
Glucocorticoid-induced tumor necrosis factor receptor-related protein (GITR) and GITR ligand (GITRL) are members of the tumor necrosis superfamily that play a role in immune cell signaling, activation, and survival. GITR is a therapeutic target for directly activating effector CD4 and CD8 T cells, or depleting GITR-expressing regulatory T cells (Tregs), thereby promoting anti-tumor immune responses. GITR activation through its native ligand is important for understanding immune signaling, but GITR structure has not been reported. Here we present structures of human and mouse GITR receptors bound to their cognate ligands. Both species share a receptor-ligand interface and receptor-receptor interface; the unique C-terminal receptor-receptor enables higher order structures on the membrane. Human GITR-GITRL has potential to form a hexameric network of membrane complexes, while murine GITR-GITRL complex forms a linear chain due to dimeric interactions. Mutations at the receptor-receptor interface in human GITR reduce cell signaling with in vitro ligand binding assays and minimize higher order membrane structures when bound by fluorescently labeled ligand in cell imaging experiments.
