Product Details FAQ Citations(1) Video Pictures Documents |Overview |Description Orphan receptor that plays a central role during humoral immunity. Promotes activated B-cell localization in the outer follicle and interfollicular regions. Its specific expression during B-cell maturation helps position B-cells appropriately for mounting T-dependent antibody responses (By similarity). Signals constitutively through G(i)-alpha, but not G(s)-alpha or G(q)-alpha. |Synonym ebi 2; EBI2; EBV induced G protein coupled receptor 2; EBV-induced G-protein coupled receptor 2; ebv-induced gene 2; Epstein Barr virus induced gene 2 (lymphocyte specific G protein coupled receptor); Epstein Barr virus induced gene 2; epstein-barr virus induced gene 2; Epstein-Barr virus-induced G-protein coupled receptor 2; G protein-coupled receptor 183; G-protein coupled receptor 183; GP183_HUMAN; gpr183; hEBI2; Lymphocyte specific G protein coupled receptor |Host Rabbit |Specificity EBI2 antibody detects endogenous levels of total EBI2. |Species Reactivity Human, Mouse |Applications WB 1:500-1:2000, ELISA(peptide) 1:20000-1:40000 |Immunogen A synthesized peptide derived from Human GPR183(Accession P32249), corresponding to amino acid residues F224-I247. |Properties |Concentration 1mg/ml |Purification The antiserum was purified by peptide affinity chromatography using SulfoLink™ Coupling Resin . |Clonality Polyclonal Antibody |Storage Temp.

Receptor for oxysterol 7-alpha,25-dihydroxycholesterol (7-alpha,25-OHC) and other related oxysterols (PubMed:21796212, PubMed:22875855, PubMed:22930711). Mediates cell positioning and movement of a number of cells by binding the 7-alpha,25-OHC ligand that forms a chemotactic gradient (By similarity). Binding of 7-alpha,25-OHC mediates the correct localization of B-cells during humoral immune responses (By similarity). Guides B-cell movement along the B-cell zone-T-cell zone boundary and later to interfollicular and outer follicular regions (By similarity). Its specific expression during B-cell maturation helps position B-cells appropriately for mounting T-dependent antibody responses (By similarity). Collaborates with CXCR5 to mediate B-cell migration; probably by forming a heterodimer with CXCR5 that affects the interaction between of CXCL13 and CXCR5 (PubMed:22913878). Also acts as a chemotactic receptor for some T-cells upon binding to 7-alpha,25-OHC ligand (By similarity). Promotes follicular helper T (Tfh) cells differentiation by positioning activated T-cells at the follicle-T-zone interface, promoting contact of newly activated CD4 T-cells with activated dendritic cells and exposing them to Tfh-cell-promoting inducible costimulator (ICOS) ligand (By similarity). Expression in splenic dendritic cells is required for their homeostasis, localization and ability to induce B- and T-cell responses: GPR183 acts as a chemotactic receptor in dendritic cells that mediates the accumulation of CD4+ dendritic cells in bridging channels (By similarity). Regulates migration of astrocytes and is involved in communication between astrocytes and macrophages (PubMed:25297897). Promotes osteoclast precursor migration to bone surfaces (By similarity). Signals constitutively through G(i)-alpha, but not G(s)-alpha or G(q)-alpha (PubMed:21673108, PubMed:25297897). Signals constitutively also via MAPK1/3 (ERK1/2) (By similarity). |tissuespecificity Expressed abundantly in lymphoid tissues such as spleen and lymph node, and in B- and T-lymphocytes (PubMed:16540462, PubMed:8383238). Also highly expressed in lung, heart and gastrointestinal tract, and weakly expressed in the urogenital system and brain (PubMed:16540462, PubMed:8383238). Expressed in astrocytes (PubMed:25297897). |Cellular localization Plasma Membrane; |UniProt P32249 | Western blot analysis of EBI2 expression in A431 whole cell lysate ,The lane on the left is treated with the antigen-specific peptide. |Tips:This product is for research use only.
