FunctionHigh affinity receptor for the C-C type chemokines CCL17/TARC and CCL22/MDC. 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.
Tissue specificityPredominantly 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.
Sequence similaritiesBelongs to the G-protein coupled receptor 1 family.
modificationsIn natural killer cells, CCL22 binding induces phosphorylation on yet undefined Ser/Thr residues, most probably by beta-adrenergic receptor kinases 1 and 2.
Cellular localizationCell membrane.

Spectral Confocal Microscopy of CHO cells using ab59550 at 1 µg/106 cells . CHO cells were transiently transfected with an expression vector encoding CCR4. Binding of ab59550 was visualized with a FITC-conjugated secondary antibody (green). Actin filaments are labeled with Alexa Fluor-555 Phalloidin (red). Cell nuclei are stained with DAPI (blue).
FACS analysis of BOSC23 cells using ab59550 at 1.2 µg/ 106 cells. BOSC23 cells were transiently transfected with an expression vector encodingeither CCR4 (red curve) or an irrelevant protein(control transfectant). Binding of ab59550 was detected with a PE conjugated secondary antibody.
