Uniprot Function Description
Acts as a ligand for C-C chemokine receptor CCR6. Signals through binding and activation of CCR6 and induces a strong chemotactic response and mobilization of intracellular calcium ions (PubMed:9862452, PubMed:20068036). The ligand-receptor pair CCL20-CCR6 is responsible for the chemotaxis of dendritic cells (DC), effector/memory T-cells and B-cells and plays an important role at skin and mucosal surfaces under homeostatic and inflammatory conditions, as well as in pathology, including cancer and autoimmune diseases (PubMed:21376174). CCL20 acts as a chemotactic factor that attracts lymphocytes and, slightly, neutrophils, but not monocytes (By similarity). Involved in the recruitment of both the proinflammatory IL17 producing helper T-cells (Th17) and the regulatory T-cells (Treg) to sites of inflammation (PubMed:19050256). Required for optimal migration of thymic natural regulatory T cells (nTregs) and DN1 early thymocyte progenitor cells (PubMed:24638065). Positively regulates sperm motility and chemotaxis via its binding to CCR6 which triggers Ca2+ mobilization in the sperm which is important for its motility (PubMed:25122636). May be involved in formation and function of the mucosal lymphoid tissues by attracting lymphocytes and dendritic cells towards epithelial cells (PubMed:10064080).
Sample type
Recommended sample types are plasma and serum. A range of additional sample types are compatible with the technology (PEA), including citrate plasma, heparin plasma, cerebrospinal fluid, (CSF), tissue and cell lysates, fine needle biopsies, microdialysis fluid, cell culture media, dried blood spots, synovial fluid, saliva, plaque extract and microvesicles. Please note that protein expression levels are expected to vary between different sample types. Certain assays are differentially affected by interfering substances such as hemolysate. Download any of our Data Validation documents or contact support@olink.com for more information.
Precision
Precision (repeatability) is calculated from quantified data (pg/mL) within the limits of quantification: LOQ.
Analytical measuring range
The technical data reported below refers to the measured values generated during the assay validation process using recombinant antigens. Per default, Olink Target 48 products deliver data in absolute protein concentrations (pg/mL) using the Calibrator built into the system.
Sensitivity plot
The calibrator curve shown below visualizes the analytical measuring range determined during the validation process using recombinant antigen. Please note that this is shown for reference only and CANNOT be used to e.g. convert NPX values to absolute concentrations. The vertical dotted lines represent lower limit of quantification (LLOQ) and upper limit of quantification (ULOQ) respectively. The solid horizontal line indicates the limit of detection (LOD).
