CXCL7 stimulates DNA synthesis, mitosis, glycolysis, intracellular cAMP accumulation, prostaglandin E2 secretion, and synthesis of hyaluronic acid and sulfated glycosaminoglycan. It also stimulates the formation and secretion of plasminogen activator by human synovial cells. Recombinant Rat CXCL7 contains 62 amino acids which is a single non-glycosylated polypeptide chain. In addition, The rat CXCL7 shares 58 % and 77 % a.a. sequence identity with human and mouse CXCL7.
