Chemokine (C-X-C motif) ligand 10 (CXCL10) or IP-10[1] is a small cytokine belonging to the CXC chemokine family that is also known as 10 kDa interferon-gamma-induced protein (γ-IP10 or IP-10). CXCL10 is secreted by several cell types in response to IFN-γ. These cell types include monocytes, endothelial cells and fibroblasts.[2] CXCL10 has been attributed to several roles, such as chemoattraction for monocytes/macrophages, T cells, NK cells, and dendritic cells, promotion of T cell adhesion to endothelial cells, antitumor activity, and inhibition of bone marrow colony formation and angiogenesis.[3][4] The gene for CXCL10 is located on human chromosome 4 in a cluster among several other CXC chemokines.[5] This chemokine elicits its effects by binding to the cell surface chemokine receptor CXCR3.[6]. The three-dimensional crystal structure of this chemokine has been determined under 3 different conditions to a resolution of up to 1.92A.[7] The Protein Data Bank accession codes for the structures of CXCL10 are 1lv9,1o7y,1o7z and 1o80.
