    SUBCELLULAR LOCALIZATION     intracellular
  • colocalizes around lipid droplets with perilipin, a regulator of lipolysis
  • localizes to both the cytoplasm and the nucleus in human white adipocytes
  • basic FUNCTION
  • activator of apoptosis
  • playing an important role in lipolysis regulation and metabolic complications of obesity, which is at least in part mediated by cross-talk between CIDEA and TNF-alpha
  • playing a role in adipose tissue energy expenditure
  • mitochondrial protein that negatively regulates the activity of the BAT uncoupling protein UCP1
  • Cide domain-containing proteins play an important role in sequestration of triglyceride within adipocytes, promoting whole-body insulin sensitivity
  • plays a central role in controlling metabolic flux in human adipose tissues through its regulation of fat storage in lipid droplets
  • playing a role in lipid-droplet structure or function
  • playing important roles in maintaining triglyceride stores in lean and obese individuals
  • involved in adipose tissue loss in cancer cachexia and this may, at least in part, be due to its ability to inactivate pyruvate dehydrogenase complex (
  • CIDEA and CIDEC are novel genes regulated by insulin in human adipocytes and may play key roles in the effects of insulin, such as anti-apoptosis and lipid droplet formation (
  • CIDEA and CIDEC are closely involved in the progression of hepatic steatosis, and TIMP1 inhibits CIDEA gene expression through SREBF1 regulation
  • may prevent lipolysis by binding and shielding lipid droplets from lipase association
  • CELLULAR PROCESS cell life, cell death/apoptosis
    a component
    small molecule
  • binds to liver X receptors (NR1H2, NR1H3) and regulates their activity (could therefore be of importance for the regulation of metabolic processes in human adipose tissue)
