Secondary Information

Protein Function adipogenesis, glucose homeostasis, food intake and body weight.chemerin functions through Gi proteins to activate L-type Ca2+ channel and elicits a dose-dependent calcium influx in vascular smooth muscle cells, which underlies chemerin-induced vasocontraction and hypertension.Chemerin specifically bind and activate CMKLR1, which leads to Ca2+-mobilization and chemotaxis in dendritic cells (DC).
Biochemical Properties C terminal has YFPGQFAFS which acts as the most active fragment.

Significance of PTMs Secreted in an inactive precursor form, prochemerin, which is proteolytically processed by a variety of extracellular proteases to generate forms with differing levels of bioactivity.After truncation of the 20 amino acid N-terminal signal peptide, chemerin is secreted as 143 residue prochemerin
Additional Comments Increased serum chemerin that occurs with obesity is highly correlated with the development of Type 2 diabetes mellitus in humans.
