Description
CCL25 (C-C Motif Chemokine Ligand 25), also known as TECK (Thymus-Expressed Chemokine), is a chemokine that selectively binds to the receptor CCR9. It plays a critical role in the homing of T-cell precursors to the thymus, T-cell development, and the recruitment of lymphocytes to the small intestine. CCL25 is predominantly expressed in the thymus and small intestine, and its dysregulation is implicated in inflammatory bowel disease, colorectal cancer, and autoimmune conditions.

Protein Summary
CCL25 is a 150-amino-acid secreted chemokine containing four conserved cysteine residues characteristic of the CC chemokine family. It is synthesized as a precursor with a 22-amino-acid signal peptide. The mature protein binds specifically to CCR9, a G-protein-coupled receptor, to induce chemotaxis of immature thymocytes, memory T cells, and dendritic cells. CCL25 is essential for T-cell development in the thymus and for gut-specific immune surveillance.
