This gene encodes a G protein-coupled receptor with selectivity for three chemokines, termed CXCL9/Mig (monokine induced by interferon-g), CXCL10/IP10 (interferon-g-inducible 10 kDa protein) and CXCL11/I-TAC (interferon-inducible T cell a-chemoattractant). Binding of chemokines to this protein induces cellular responses that are involved in leukocyte traffic, most notably integrin activation, cytoskeletal changes and chemotactic migration. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. One of the isoforms (CXCR3-B) shows high affinity binding to chemokine, CXCL4/PF4 (PMID:12782716).

A study in rats demonstrated that the CXCR3 was significantly downregulated in the prefrontal cortex at 2 hours after a binge methamphetamine regimen, indicating region-specific transcriptional changes in microglia and infiltrating macrophages [Kays et al. DOI:10.3390/brainsci9120340]. A review of single-cell sequencing in mice following myocardial infarction identified the CXCR3 as a characteristic marker for effector T-cells, specifically within the CD4-C2-CXCR3 cluster, and noted its downregulation in the PFC at 2h post-METH as part of a broader inflammatory response [Bian et al. DOI:10.3892/mmr.2025.13680]. A study in rats demonstrated that the CXCR3 (Cxcr3) mRNA and protein were markedly upregulated in cortical white matter astrocytes after 10–11 psi blast wave exposure, with little change after 5 psi, correlating with vascular injury and inflammatory pathways in mild blast traumatic brain injury [Balaban et al. DOI:10.1016/j.jneumeth.2016.02.001].
