Recombinant Human VCC-1/CXCL17

Description :
FAQ COA 已发表文献 CXCL17 also named dendritic cell and monocyte chemokine-like protein (DMC) and VEGF co-regulated chemokine 1 (VCC-1), is a small cytokine belonging to the CXC chemokine family. CXCL17 was the last chemokine ligand to be described and is the 17th member of the CXC chemokine family. Its strategic expression in mucosal tissues suggests that it is involved in innate immunity and/or sterility of the mucosa. Mature human DMC shares 73%, 71% and 64% amino acid sequence identity with bovine, mouse and rat DMC, respectively. It may be a housekeeping chemokine regulating recruitment of nonactivated blood monocytes and immature dendritic cells into tissues and may play a role in the innate defense against infections.CXCL17 also has a role in angiogenesis of importance for tumour development.
