Chemokine (C-X-C motif) ligand 16 (CXCL16) is a small cytokine belonging to the CXC chemokine family. Larger than other chemokines (with 254 amino acids) CXCL16 is composed of a CXC chemokine domain a mucin-like stalk a transmembrane domain and a cytoplasmic tail containing a potential tyrosine phosphorylation site that may bind SH2. These are unusual features for a chemokine and allow CXCL16 to be expressed as a cell surface bound molecule as well as a soluble chemokine.
