Gene Description

CXCR3 is a seven-transmembrane chemokine receptor that recognizes CXCL9, CXCL10 and CXCL11 and coordinates lymphocyte recruitment through G-protein signaling. Human alternative isoforms differ in ligand recognition and downstream growth responses; CXCR3-B also recognizes CXCL4 and mediates angiostatic responses.

Summary: negative regulation of endothelial cell proliferation: The CXCR3-B isoform experiments support endothelial growth inhibition, cAMP-linked signaling and apoptosis. These are real isoform/context-dependent activities but do not describe the principal lymphocyte-trafficking function of CXCR3-A. The experimental isoform context should accompany interpretation.
