| Tissue Specificity | Synthesized exclusively by adipocytes and secreted into plasma. |
| Post Translational Modifications | HMW complexes are more extensively glycosylated than smaller oligomers. Hydroxylation and glycosylation of the lysine residues within the collagen-like domain of adiponectin seem to be critically involved in regulating the formation and/or secretion of HMW complexes and consequently contribute to the insulin-sensitizing activity of adiponectin in hepatocytes. O-glycosylated. Not N-glycosylated O-linked glycans on hydroxylysine residues consist of Glc-Gal disaccharides bound to the oxygen atom of post-translationally added hydroxyl groups. O-linked glycosylation in the N-terminal is disialylated with the structure Neu5Acalpha2->8Neu5Acalpha2->3Gal. Sialylated by alpha 2,8-sialyltransferase III. Succination of Cys-39 by the Krebs cycle intermediate fumarate, which leads to S-(2-succinyl)cysteine residues, inhibits polymerization and secretion of adiponectin. Adiponectin is a major target for succination in both adipocytes and adipose tissue of diabetic mice. It was proposed that succination of proteins is a biomarker of mitochondrial stress and accumulation of Krebs cycle intermediates in adipose tissue in diabetes and that succination of adiponectin may contribute to the decrease in plasma adiponectin in diabetes. |
| Function | Important adipokine involved in the control of fat metabolism and insulin sensitivity, with direct anti-diabetic, anti-atherogenic and anti-inflammatory activities. Stimulates AMPK phosphorylation and activation in the liver and the skeletal muscle, enhancing glucose utilization and fatty-acid combustion. Antagonizes TNF-alpha by negatively regulating its expression in various tissues such as liver and macrophages, and also by counteracting its effects. Inhibits endothelial NF-kappa-B signaling through a cAMP-dependent pathway. May play a role in cell growth, angiogenesis and tissue remodeling by binding and sequestering various growth factors with distinct binding affinities, depending on the type of complex, LMW, MMW or HMW. |
