Enables identical protein binding activity. Involved in positive regulation of adiponectin secretion and positive regulation of cytokine production. Acts upstream of or within glucose homeostasis; negative regulation of gluconeogenesis; and positive regulation of intracellular signal transduction. Located in extracellular space. Part of protein-containing complex. Is expressed in several structures, including central nervous system; epithelium; jaw; metanephros; and musculoskeletal system. Orthologous to human C1QTNF3 (C1q and TNF related 3). [provided by Alliance of Genome Resources, Apr 2022]
