|Detection of CCR6 in HEK293 Human Cell Line Transfected with Rat CCR6 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with either (A) rat CCR6 or (B) irrelevant transfectant and eGFP was stained with Mouse Anti-Rat CCR6 Alexa Fluor® 405‑conjugated Monoclonal Antibody (Catalog # FAB8320V). Quadrant markers were set based on control antibody staining (Catalog # IC0041V). View our protocol for Staining Membrane-associated Proteins.|
CCR6 is an approximately 45 kDa G-protein linked seven transmembrane domain receptor that binds the chemokine CCL20/MIP-3 alpha. Among hematopoietic cells, CCR6 is expressed on B cells, immature dendritic cells, neutrophils, and various T cell subsets (e.g. CD4+ T cells, regulatory T cells, effector memory Th17 cells, and g/d T cells). It is upregulated in several cancers, Alzheimer’s brain, and the airways in obstructive pulmonary disease. CCR6 plays an important role in mucosal immunity, IgE mediated allergic reactions, immune cell infiltration into sites of inflammation, and tumor cell invasiveness. It also promotes chemotaxis and tumor angiogenesis in response to beta defensins. Rat CCR6 shares 74% and 87% amino acid sequence identity with human and mouse CCR6, respectively.
