Publication Abstract from PubMed

Glucocorticoid-induced TNF receptor ligand (GITRL), a recently identified member of the TNF superfamily, binds to its receptor, GITR, on both effector and regulatory T cells and generates positive costimulatory signals implicated in a wide range of T cell functions. In contrast to all previously characterized homotrimeric TNF family members, the mouse GITRL crystal structure reveals a previously unrecognized dimeric assembly that is stabilized via a unique "domain-swapping" interaction. Consistent with its crystal structure, mouse GITRL exists as a stable dimer in solution. Structure-guided mutagenesis studies confirmed the determinants responsible for dimerization and support a previously unrecognized receptor-recognition surface for mouse GITRL that has not been observed for any other TNF family members. Taken together, the unique structural and biochemical behavior of mouse GITRL, along with the unusual domain organization of murine GITR, support a previously unrecognized mechanism for signaling within the TNF superfamily.
