|Other Names||C-C chemokine receptor type 4, C-C CKR-4, CC-CKR-4, CCR-4, CCR4, K5-5, CD194, CCR4, CMKBR4|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||High affinity receptor for the C-C type chemokines CCL17/TARC, CCL22/MDC and CKLF isoform 1/CKLF1. The activity of this receptor is mediated by G(i) proteins which activate a phosphatidylinositol-calcium second messenger system. Can function as a chemoattractant homing receptor on circulating memory lymphocytes and as a coreceptor for some primary HIV-2 isolates. In the CNS, could mediate hippocampal-neuron survival.|
|Cellular Location||Cell membrane; Multi-pass membrane protein.|
|Tissue Location||Predominantly expressed in the thymus, in peripheral blood leukocytes, including T-cells, mostly CD4+ cells, and basophils, and in platelets; at lower levels, in the spleen and in monocytes. Detected also in macrophages, IL-2-activated natural killer cells and skin-homing memory T-cells, mostly the ones expressing the cutaneous lymphocyte antigen (CLA). Expressed in brain microvascular and coronary artery endothelial cells|

The protein encoded by this gene belongs to theG-protein-coupled receptor family . It is a receptor for the CCchemokine - MIP-1, RANTES, TARC and MCP-1. Chemokines are a groupof small polypeptide, structurally related molecules that regulatecell trafficking of various types of leukocytes. The chemokinesalso play fundamental roles in the development, homeostasis, andfunction of the immune system, and they have effects on cells ofthe central nervous system as well as on endothelial cells involvedin angiogenesis or angiostasis.
