Recombinant mouse adiponectin is typically produced in Escherichia coli and includes a His tag for purification purposes. The His tag is a sequence of histidine residues added to the protein to facilitate its purification using metal affinity chromatography . The recombinant form of mouse adiponectin is a 27.2 kDa protein containing 251 amino acid residues .
Adiponectin is an important adipokine involved in the control of fat metabolism and insulin sensitivity. It stimulates AMPK phosphorylation and activation in the liver and skeletal muscle, enhancing glucose utilization and fatty acid combustion . Additionally, adiponectin antagonizes TNF-alpha by negatively regulating its expression in various tissues such as the liver and macrophages .
Adiponectin levels are inversely correlated with obesity and insulin resistance. Lower levels of adiponectin are associated with increased risk of metabolic disorders such as type 2 diabetes and cardiovascular diseases . The protein’s ability to enhance insulin sensitivity and reduce inflammation makes it a potential therapeutic target for treating these conditions.
