CXCL10 also known as IP-10 is belonging to the CXC chemokine family. It is encoded by the CXCL10 gene, and in rat it is also named the Mob-1 gene. This gene was identified on the basis of differential expression in rat embryo fibroblasts. CXCL10 elicits its effects by binding to the cell surface chemokine receptor CXCR3. CXCL10 has been shown to be a chemoattractant for activated T-lymphocytes and monocytes/macrophages. It also has other roles, such as promotion of T cell adhesion to endothelial cells, and inhibition of bone marrow colony formation and angiogenesis. Rat CXCL10 shares approximately 68 % amino acid sequence identity with human CXCL10.
