| + | [[http://www.uniprot.org/uniprot/US28_HCMVA US28_HCMVA]] Receptor for a C-C type chemokine. Binds to a number of different CC-chemokines including CCL5/RANTES, CCL2/MCP-1, CCL3/MIP-1-alpha as well as CX3CL1/Fractalkine. Transduces signals resulting in the activation of MAP kinase signaling pathways and augmentation of intracellular calcium ion levels, leading to alterations in chemotactic behavior of vascular smooth muscle cells and macrophages. The US28 receptor also exhibits high levels of agonist-independent signaling activity and agonist-independent endocytosis. Interacts with endogenous Gaq/11 subunits and thereby constitutively activates phospholipase C.<ref>PMID:11050102</ref> <ref>PMID:7961796</ref> [[http://www.uniprot.org/uniprot/X3CL1_HUMAN X3CL1_HUMAN]] The soluble form is chemotactic for T-cells and monocytes, but not for neutrophils. The membrane-bound form promotes adhesion of those leukocytes to endothelial cells. May play a role in regulating leukocyte adhesion and migration processes at the endothelium. Binds to CX3CR1.<ref>PMID:21829356</ref> | ||
