Mouse CCL25/TECK Antibody (89827)

CCL25 (thymus-expressed chemokine), also known as TECK (thymus-expressed chemokine), is a CC chemokine that is distantly related (twenty-some % amino acid sequence identity) to other CC chemokines. Mouse CCL25 cDNA encodes a 144 amino acid residue precursor protein with a 23 amino acid residue signal peptide that is cleaved to yield a 121 residue mature protein.  Mouse CCL25 shares 49% amino acid sequence identity with 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. CCL25 functions through interactions with CCR9 and is chemotactic for activated macrophages, dendritic cells and thymocytes (1).
