|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||CKRB/CKR11 Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||CCBP2, CCR11, CCRL1, VSHK1|
|Function||Atypical chemokine receptor that controls chemokine levels and localization via high-affinity chemokine binding that is uncoupled from classic ligand-driven signal transduction cascades, resulting instead in chemokine sequestration, degradation, or transcytosis. Also known as interceptor (internalizing receptor) or chemokine-scavenging receptor or chemokine decoy receptor. Acts as a receptor for chemokines CCL2, CCL8, CCL13, CCL19, CCL21 and CCL25. Chemokine-binding does not activate G-protein-mediated signal transduction but instead induces beta-arrestin recruitment, leading to ligand internalization. Plays an important role in controlling the migration of immune and cancer cells that express chemokine receptors CCR7 and CCR9, by reducing the availability of CCL19, CCL21, and CCL25 through internalization. Negatively regulates CXCR3-induced chemotaxis. Regulates T-cell development in the thymus.|
|Cellular Location||Early endosome. Recycling endosome. Cell membrane; Multi-pass membrane protein. Note=Predominantly localizes to endocytic vesicles, and upon stimulation by the ligand is internalized via caveolae. Once internalized, the ligand dissociates from the receptor, and is targeted to degradation while the receptor is recycled back to the cell membrane|
|Tissue Location||Predominantly expressed in heart. Lower expression in lung, pancreas, spleen, colon, skeletal muscle and small intestine.|

CCR11 is a G protein-coupled, seven-transmembrane receptor protein that plays a role in the chemotaxis and trafficking of leukocytes. Showing similar binding affinities as does CCR2 and CCR10 (1,2), CCR11 has been shown to specifically bind the MCP- (monocyte chemoattractant protein) family of chemokines, including MCP-4, MCP-2, and MCP-1. It was also shown to bind eotaxin (3). Though CCR11 shares functional similarity to CCR2 because it recognizes members of the MCP family, CCR11 has a distinct expression pattern (3).
