Chemokine (C-X-C motif) ligand 9 (CXCL9) is a small cytokine belonging to the CXC chemokine family that is also known as Monokine induced by gamma interferon (MIG). CXCL9 is a T-cell chemoattractant, which is induced by IFN-γ. It is closely related to two other CXC chemokines called CXCL10 and CXCL11, whose genes are located near the gene for CXCL9 on human chromosome 4.[1][2] CXCL9, CXCL10 and CXCL11 all elicit their chemotactic functions by interacting with the chemokine receptor CXCR3.[3]

Neutrophil collagenase/matrix metalloproteinase 8 (MMP-8) degrades CXCL9 and cleaves CXCL10 at two positions.

Gelatinase B/matrix metalloproteinase 9 (MMP-9) degrades CXCL10 and cleaves CXCL9 at three different sites in its extended carboxy-terminal region.

Interactions[edit]

CXCL9 has been shown to interact with CXCR3.[4][5]
