Chemokine (C-C motif) ligand 27 (CCL27) is a small cytokine belonging to the CC chemokine family also known under the names IL-11 R-alpha-locus chemokine (ILC), Skinkine, ESkine and Cutaneous T-cell-attracting chemokine (CTACK). It is associated with homing of memory T lymphocytes to the skin, and plays a role in T cell-mediated inflammation of the skin. CCL27 is expressed in numerous tissues, including gonads, thymus, placenta and skin. It elicits its chemotactic effects by binding to the chemokine receptor CCR10. The gene for CCL27 is located on human chromosome 9.
