Protein Structure

UniProt Annotation

Function

Receptor for oxysterol 7-alpha,25-dihydroxycholesterol (7-alpha,25-OHC) and other related oxysterols. Binding of f 7- alpha,25-OHC mediates the correct localization of B-cells during humoral immune responses. 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. Signals constitutively also via MAPK1/3 (ERK1/2) (By similarity). {ECO:0000250}.

Subcellular Localization

Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
