Description
AITRL, a type II transmembrane protein, is a ligand for glucocorticoid-induced TNFR-related protein (GITR). When AITRL binds to GITR, GITR can produce costimulatory signals that regulate T-cell proliferation and effector functions. GITR/AITRL interaction plays a role in the pathogenesis of tumor, inflammation, as well as autoimmune diseases. Besides, AITRL plays a role in endothelial cells (EC)-activation and increases STAT-1 phosphorylation and the expression of adhesion molecules (VCAM-1, ICAM-1). AITRL/TNFSF18 Trimer Protein, Human (HEK293, His-Flag) is a recombinant human AITRL (Q72-S199) trimer with N-terminal His and Flag tag, which is expressed in HEK293
