Anti-CXCL16 Antibody Picoband®

CXCL16, Chemokine (C-X-C motif) ligand 16, is a small cytokine belonging to the CXC chemokine family. Larger than other chemokines (with 254 amino acids), CXCL16 is composed of a CXC chemokine domain, a mucin-like stalk, a transmembrane domain and a cytoplasmic tail containing a potential tyrosine phosphorylation site that may bind SH2. By somatic cell hybrid analysis, the CXCL16 gene is mapped to 17p13, a locus separate from all other known chemokines. Chemotaxis assays found that CXCL16 induced a strong chemotactic response in activated CD8 T cells. In addition, CXCL16 induced calcium mobilization.

C-X-C motif chemokine 16; Scavenger receptor for phosphatidylserine and oxidized low density lipoprotein; SR-PSOX; Small-inducible cytokine B16; Transmembrane chemokine CXCL16; CXCL16; SCYB16, SRPSOX; UNQ2759/PRO6714

E. coli-derived human CXCL16 recombinant protein (Position: N30-A196) . Human CXCL16 shares 47% and 45.7% amino acid (aa) sequence identity with mouse and rat CXCL16, respectively.

Expressed in T-cell areas. Expressed in spleen, lymph nodes, lung, kidney, small intestine and thymus. Weak expression in heart and liver and no expression in brain and bone marrow.

Acts as a scavenger receptor on macrophages, which specifically binds to OxLDL (oxidized low density lipoprotein), suggesting that it may be involved in pathophysiology such as atherogenesis (By similarity) . Induces a strong chemotactic response. Induces calcium mobilization. Binds to CXCR6/Bonzo. .
