Receptor for the C-X-C chemokines cxcl11.1 and cxcl11.6 (PubMed:25573892). Promotes macrophage chemotaxis to sites of bacterial infection (PubMed:20424185, PubMed:25573892). Detected in developing macrophages at 28 hours post-fertilization (PubMed:20424185). Continues to be expressed in macrophages at 2 and 6 days post-fertilization (dpf) (PubMed:25573892). Also detected in neutrophils at 2 and 6 dpf (PubMed:25573892). Viable with no significant effect on survival (PubMed:25573892). Macrophage and neutrophil counts are normal (PubMed:25573892). Macrophage migration in response to cxcr3.2-independent stimuli is not affected, although the basal migration rate is reduced (PubMed:25573892). Macrophage migration to sites of bacterial infection by S.typhimurium or M.marinum is reduced (PubMed:20424185, PubMed:25573892). Dissemination of bacterial infection to distant sites and granuloma formation is also reduced (PubMed:25573892). Belongs to the G-protein coupled receptor 1 family.
