Function
High 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 specificity
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. -
Sequence similarities
Belongs to the G-protein coupled receptor 1 family. -
Post-translational
modificationsIn natural killer cells, CCL22 binding induces phosphorylation on yet undefined Ser/Thr residues, most probably by beta-adrenergic receptor kinases 1 and 2. -

Anti-CCR4 antibody (ab1669) at 1 µg/ml + Human thymus tissue lysate - total protein (ab30146) at 10 µg
Secondary
Rabbit polyclonal to Goat IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 42 kDa
Observed band size: 55 kDa why is the actual band size different from the predicted?
Additional bands at: 100 kDa, 37 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 12 minutes
CCR4 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
