ID:CCR3_HUMAN DESCRIPTION: RecName: Full=C-C chemokine receptor type 3; Short=C-C CKR-3; Short=CC-CKR-3; Short=CCR-3; Short=CCR3; Short=CKR3; AltName: Full=Eosinophil eotaxin receptor; AltName: CD_antigen=CD193; FUNCTION: 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. SUBUNIT: Binds to HIV-1 Tat. SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: In eosinophils as well as trace amounts in neutrophils and monocytes. MISCELLANEOUS: Overexpression of CCR3 together with its ligands appears to be a characteristic of ulcerative colitis (UC). The production of CCR3 ligands by human colonic epithelial cells suggests further that the epithelium can play a role in modulating pathological T-cell-mediated mucosal inflammation (PubMed:21077277). SIMILARITY: Belongs to the G-protein coupled receptor 1 family. WEB RESOURCE: Name=Wikipedia; Note=CC chemokine receptors entry; URL="http://en.wikipedia.org/wiki/CC_chemokine_receptors";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
