Eotaxin2, also named MPIF2 and Ckβ6, is a CC chemokine that is designated CCL24. Eotaxin2 cDNA encodes a 10.5 kDa, 119 amino acid residue precursor protein with a 26 aa residue signal peptide that is cleaved to generate a mature protein predicted to contain 93 amino acid residues with an N-glycosylation site. C-terminally truncated variants with 78, 73, 75 and 76 residues have also been described. Eotaxin 2 shares 40%, 42% and 39% amino acid sequence identity with other CC chemokines CCL7/MCP3, CCL3/MIP1α, and CCL11/Eotaxin, respectively. Eotaxin2 mRNA is weakly expressed in activated monocytes and T lymphocytes. Recombinant Eotaxin2 induces chemotaxis of eosinophils, basophils, and resting T lymphocytes, but not monocytes or activated T lymphocytes. Eotaxin2 also suppresses colony formation by high proliferative multipotential hematopoietic progenitors. On eosinophils, the effects of Eotaxin2, Eotaxin and CCL13/MCP4 are mediated by the receptor CCR3.

CCL25 (thymus-expressed chemokine) is a CC chemokine that is distantly related (approximately 20% amino acid sequence identity) to other CC chemokines. Human CCL25 cDNA encodes a 150 aa precursor protein with a 23 aa signal peptide that is cleaved to yield a 127 aa mature protein. Mouse CCL25 cDNA has also been cloned and shown to encode a 144 aa protein that exhibits 49% aa sequence identity to human CCL25. The expresssion of human and mouse CCL25 was shown to be highly restricted to the thymus and small intestine. Although dendritic cells have been demonstrated to be the source of CCL25 production in the thymus, dendritic cells derived from bone marrow do not express CCL25. The gene for mouse CCL25 has been mapped to chromosome 8 rather than chromosome 11 where many mouse CC chemokines are clustered. Recombinant human and mouse CCL25 are chemotactic for activated macrophages, dendritic cells and thymocytes. CCL25 is also a specific agonist for the CCR9 chemokine receptor.

CTACK or CCL-27 is a keratinocyte-derived CC chemokine which signals through the CCR10 receptor. Both CTACK and CCR10 are expressed in normal and irritated epithelial cells. CTACK selectively attracts CLA+ T-cells and directs them into the skin. CTACK contains the four highly conserved cysteine residues present in most CC chemokines. The mature protein contains 88 amino acid residues. Recombinant human CTACK is a 10.2 kDa protein containing 88 amino acid residues.
