Predicted to enable tumor necrosis factor receptor binding activity. Acts upstream of or within several processes, including lymph node development; positive regulation of immune response; and positive regulation of interferon-gamma production. Predicted to be located in extracellular space. Is expressed in several structures, including extraembryonic component; gut; hemolymphoid system; liver; and reproductive system. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); autoimmune disease (multiple); glucose metabolism disease (multiple); leishmaniasis (multiple); and lung disease (multiple).
