The protein encoded by this gene is a receptor for C-C type chemokines. It belongs to family 1 of the G protein-coupled receptors. This receptor binds and responds to a variety of chemokines, including eotaxin (CCL11), eotaxin-3 (CCL26), MCP-3 (CCL7), MCP-4 (CCL13), and RANTES (CCL5). It is highly expressed in eosinophils and basophils, and is also detected in TH1 and TH2 cells, as well as in airway epithelial cells. This receptor may contribute to the accumulation and activation of eosinophils and other inflammatory cells in the allergic airway. It is also known to be an entry co-receptor for HIV-1. This gene and seven other chemokine receptor genes form a chemokine receptor gene cluster on the chromosomal region 3p21. Alternatively spliced transcript variants have been described.

GeneCards Summary for CCR3 Gene
CCR3 (C-C Motif Chemokine Receptor 3) is a Protein Coding gene. Diseases associated with CCR3 include Folliculotropic Mycosis Fungoides and Aids Dementia Complex. Among its related pathways are CCR5 Pathway in Macrophages and Peptide ligand-binding receptors. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and C-C chemokine receptor activity. An important paralog of this gene is CCR1.
UniProtKB/Swiss-Prot Summary for CCR3 Gene
Receptor for a C-C type chemokine. Binds to eotaxin, eotaxin-3, MCP-3, MCP-4, RANTES and MIP-1 delta. Subsequently transduces a signal by increasing the intracellular calcium ions level. Alternative coreceptor with CD4 for HIV-1 infection.
Chemokine CC receptors (CCRs) predominantly recognize CC chemokines. CC chemokines are distinguished by having four conserved cysteines, with the first two cysteines being adjacent to each other. There are 10 chemokine CC receptors.
