功能
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. -
组织特异性
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. -
序列相似性
Belongs to the G-protein coupled receptor 1 family. -
翻译后修饰
In natural killer cells, CCL22 binding induces phosphorylation on yet undefined Ser/Thr residues, most probably by beta-adrenergic receptor kinases 1 and 2. -

Flow Cytometry - Anti-CCR4 antibody (ab1669)This image is courtesy of an anonymous Abreviewab1669 staining CCR4 in Mouse whole blood by Flow Cytometry. Red blood cells were lysed in PBS + 1% BSA and 0.01% sodium azide and fixed in paraformaldehyde. The sample was incubated with the primary antibody (1/100 in PBS + 1% BSA and 0.01% sodium azide) for 1 hour at 4°C. A biotin-conjugated Donkey anti-goat IgG polyclonal (1/200) was used as the secondary antibody.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CCR4 antibody (ab1669)IHC image of CCR4 staining in human spleen formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab1669, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times. -

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.
