CCR4 (human) full length protein-VLP

Virus-like particles (VLPs) are self-assembling multi-protein nanoparticles with similar structural organization and conformation as viruses but without viral genome. The size of the VLP is about 100-150nm. It is secreted from the surface of the cells that express target membrane proteins (MPs). The purified VLPs have the target MPs inserted in a complete bilayer phospholipid membrane structure, mimic the natural membrane-penetrating state of the protein (Figure 3). VLPs can be used for routine biochemical analysis, including ELISA, SPR affinity analysis, phage display screenings, protein labeling and cell binding experiments, Flow virometry analysis, etc. It can also be used as functional protein antigens to develop active antibodies with high drug potentials because the target protein on VLP exhibits a state like its native state on the cell surface. Protein 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.
