Chemerin, also known as retinoic acid receptor responder 2 (RARRES2) and tazarotene induced gene 2 (TIG2), is a chemoattractant protein for cells expressing G-protein-linked receptor chemokine-like receptor 1 (CMKLR1, ChemR23 or GPCR-DEZ). The protein is synthesized as a secreted precursor, prochemerin (18 kDa), which is poorly active. Upon proteolytic removal of the last six amino acids, prochemerin is converted into mature active chemerin (15-16 kDa) that acts as a strong and highly specific agonist of its receptor CMKLR1. Chemerin is a newly described adipokine with effects on adipocyte differnetiation and metabolism.
