Adipsin is also called as complement factor D, or C3 convertase activator or properdin factor D, because they are identical molecule, mature protein aa 26-253, ~22kD. It is belonged to a serine protease that is secreted by adipocytes. Adipocytes synthesize and store energy in periods of nutritional abundance and mobilize lipids during starvation and other times of need. The switch from energy storage to expenditure is finely regulated by a variety of hormones. In order to accomplish these complex tasks energy balance, adipocytes express many genes, including adipsin, involved in lipid metabolism and glucose homeostasis. Many of these genes are finely regulated during adipocyte differentiation and maturation. Several adipocyte-derived proteins act in an autocrine or paracrine fashion to control its own and other cell's cellular physiology.

The rabbit anti-human Adipsin antibody detects targets derived from human recombinant and cellular proteins at various concentrations. Cross reactivity with mouse and rat are expected from sequence similarity.
