Target Background

Receptor for C-C type chemokine. Binds and responds to a variety of chemokines, including CCL11, CCL26, CCL7, CCL13, RANTES(CCL5) and CCL15. Subsequently transduces a signal by increasing the intracellular calcium ions level. In addition acts as a possible functional receptor for NARS1.; (Microbial infection) Alternative coreceptor with CD4 for HIV-1 infection.
Gene References into Functions
  1. MACs from Familial hypercholesterolemia (FH)-MACs have an inflammatory phenotype that is characterized by the up-regulation of CCR3, CCR4, and CXCR1 under the control of miR-505-3p. These results suggest a chronic inflammatory condition in FH innate immunity cells that is not reverted by standard lipid-lowering treatment PMID: 29457550
  2. CCR3 exists as a mixture of monomers and dimers under nearly physiological conditions. The monomeric CCR3 receptor is the minimal functional unit in cellular signal transduction.
