Genes affected

C1QTNF3 (HGNC:14326): (C1q and TNF related 3) Enables identical protein binding activity. Involved in several processes, including cellular triglyceride homeostasis; negative regulation of NIK/NF-kappaB signaling; and regulation of cytokine production. Acts upstream of or within negative regulation of gluconeogenesis. Located in extracellular exosome and membrane. [provided by Alliance of Genome Resources, Apr 2022]
