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.

Applications : Binding assay/Protein-protein interaction

Review: The protein has seven transmembrane domains, making it very difficult for recombinant expression. I have purchased both of CUSABIO\'s mammalian cell and cell-free expressed products, and they have performed well in terms of activity determination, which are sufficient to meet my future application demands. I may continue to purchase in large quantities in the future.
