Note CXCR3 is a G protein-coupled receptor with selectivity for three chemokines, termed IP10 (CXCL10), Mig (CXCL9) and I-TAC (CXCL11). IP10, Mig and I-TAC belong to the structural subfamily of CXC chemokines, in which a single amino acid residue separates the first two of four highly conserved Cys residues. Binding of chemokines to CXCR3 induces cellular responses that are involved in leukocyte traffic, most notably integrin activation, cytoskeletal changes and chemotactic migration. A hallmark of CXCR3 is its prominent expression in in vitro cultured effector/memory T cells, and in T cells present in many types of inflamed tissues. In addition, IP10, Mig and I-TAC are commonly produced by local cells in inflammatory lesions, suggesting that CXCR3 and its chemokines participate in the recruitment of inflammatory cells.

DNA/RNA

Note CXCR3-A is a receptor for CXCL9, CXCL10 and CXCL11 and mediates the proliferation of human mesangial cells. CXCR3-B is a receptor for CXCL4 and also mediates the inhibitory activities of CXCL9, CXCL10 and CXCL11 on the growth of human microvascular endothelial cells. CXCR3-B may play a role in angiogenesis.
 
  The CXCR3 gene generates two distinct mRNAs.
Description Alternative splicing of the CXCR3 gene generates two distinct chemokine receptors. The CXCR3 gene generates two distinct mRNAs, resulting from alternative splicing of three different exons. The already known CXCR3, renamed CXCR3-A,results from splicing of a single intron. The first exon encodes 4 amino acids and the second exon encodes the remaining 312 amino acids. The recently identified splicing variant, CXCR3-B,results from an alternative splicing between the same donor site used by the known CXCR3-A and a novel acceptor site localized 233 base pairs upstream of the CXCR3-A acceptor site. This novel exon (exon2) encodes 51 different amino acids, which are selectively expressed in CXCR3-B.
Transcription CXCR3-A and CXCR3-B transcripts of 1.6 and 1.8 kb, respectively.

Protein

Description Size: 368 amino acids; 40660 Da.
Expression CXCR3-A and CXCR3-B are mainly expressed in the heart, kidney, liver and skeletal muscle. CXCR3-A is also expressed in the placenta.
Localisation Cell membrane; Multi-pass membrane protein.
Function Dijkstra et al. showed that human CCL21, in the absence of its primary receptor, CCR7, is a functional ligand for CXCR3, inducing chemotaxis in adult microglial cells, but not in kidney epithelial cells. CCL21 signaling through CXCR3 depends on the cellular background in which CXCR3 is expressed.
Lasagni et al. found that both CXCR3-A and CXCR3-B bound CXCL9, CXCL10, and CXCL11, but only CXCR3-B bound CXCL4 (PF4), following expression in a microvascular endothelial cell line. Overexpression of CXCR3-A induced an increase in endothelial cell survival, whereas overexpression of CXCR3-B upregulated apoptotic pathways. CXCR3B-specific monoclonal antibodies reacted with neoplastic tissue endothelial cells, providing evidence that CXCR3-B is expressed in vivo and may account for the angiostatic effects of CXC chemokines.

Implicated in

Note
  
Entity Melanoma
Prognosis Forty primary melanomas were analyzed. 57% of the tumors expressed CXCR3 and 35% expressed CXCR4 on the melanoma cells. Co-expression of both CXCR3 and CXCR4 conferred a significantly poorer outcome similar to the expression of CXCR4 alone.
Oncogenesis Several human melanoma cell lines as well as melanoma cells on macroscopically infiltrated lymph nodes express the chemokine receptors CXCR3 and CXCR4.
In a murine model with B16F10 melanoma cells, reduced CXCR3 expression by antisense RNA showed significantly reduced metastatic activities to lymph nodes.
  
  
Entity Breast cancer
Oncogenesis Activation of Ras in MDA-MB-435 and MCF-7 breast cancer cells promotes CXCL10 expression and down-regulates CXCR3-B expression to promote tumor cell proliferation.
In a murine model of metastatic breast cancer, a small molecular weight antagonist of CXCR3 inhibits lung metastasis.
  
  
Entity Colon cancer
Prognosis In 92 colon cancer samples, 31 samples (33.7%) expressed CXCR3 on cancer epithelial cells. The patients with CXCR3-positive tumors had a significantly poorer prognosis than those with CXCR3-negative tumors. In addition, the patients with tumors dobly positive for CXCR3 and CXCR4 had a significantly poorer prognosis than those with tumors positive only for CXCR4 or doubly negative.
Oncogenesis In a murine model of metastatic colon cancer, overexpression of CXCR3 significantly promotes lymph node metastasis, although metastasis to the liver or lung was unaffected.
  
  
Entity Renal cell carcinoma
Oncogenesis Real-time RT-PCR analysis showed that expression levels of I-TAC, Mig, and CXCR3 in RCC tissues were greater 14.9 times, 30.3 times, and 9.9 times, respectively, compared with the levels in the corresponding normal kidney tissues.
  
  
Entity B-cell Lymphoma
Oncogenesis CXCR3 expression was seen in 37 of 39 cases of chronic lymphocytic leukemia / small lymphocytic lymphoma, whereas mantle cell lymphoma (30 cases), follicular lymphoma (27 cases) and small noncleaved cell lymphoma (8 cases) were negative in all but 2 cases.
