Biological function summary
EBI2 supports the positioning of immune cells within secondary lymphoid organs by detecting specific chemokine gradients. It does not form part of larger complexes but instead functions independently to interpret chemotactic signals. EBI2 is important during B cell maturation orchestrating the cellular movement that is essential for executing adaptive immune responses effectively.
Pathways
EBI2 integrates into the oxysterol signaling pathway which directly impacts immune cell dynamics. Through its effects on B cell migration its function connects to the chemokine signaling pathway. EBI2 interacts with proteins like CXCR5 enabling the directed movement of B cells towards follicular dendritic cells playing a role in ensuring effective humoral immunity.

General info
Function
G-protein coupled receptor expressed in lymphocytes that acts as a chemotactic receptor for B-cells, T-cells, splenic dendritic cells, monocytes/macrophages and astrocytes (By similarity). 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).
