CCL21

Chemokine (C-C motif) ligand 21 (CCL21) is a small is_associated_with::cytokine belonging to the CC is_associated_with::chemokine family. This chemokine is also known as 6Ckine (because it has six conserved is_associated_with::cysteine residues instead of the four cysteines typical to chemokines), exodus-2, and secondary lymphoid-tissue chemokine (SLC). The is_associated_with::gene for CCL21 is located on human is_associated_with::chromosome 9. CCL21 elicits its effects by binding to a cell surface is_associated_with::chemokine receptor known as CCR7.
