CXCL11 (ITAC) is one of three chemokines known to bind the receptor CXCR3, the two others being CXCL9 (Mig) and CXCL10 (IP-10). CXCL11 differs from, the other CXCR3 ligands in both the strength and the particularities of, its receptor interactions: It has a higher affinity, is a stronger, agonist, and behaves differently when critical N-terminal residues are, deleted. The structure of CXCL11 was determined using solution NMR to, allow comparison with that of CXCL10 and help elucidate the source of the, differences. CXCL11 takes on the canonical chemokine fold but exhibits, greater conformational flexibility than has been observed for related, chemokines under the same sample conditions. Unlike related chemokines, such as IP-10 and IL-8, ITAC does not appear to form dimers at millimolar, concentrations. The origin for this behavior can be found in the solution, structure, which indicates a beta-bulge in beta-strand 1 that distorts the, dimerization interface used by other CXC chemokines.

[https://www.uniprot.org/uniprot/CXL11_HUMAN CXL11_HUMAN] Chemotactic for interleukin-activated T-cells but not unstimulated T-cells, neutrophils or monocytes. Induces calcium release in activated T-cells. Binds to CXCR3. May play an important role in CNS diseases which involve T-cell recruitment. May play a role in skin immune responses.
