ID:GP183_HUMAN DESCRIPTION: RecName: Full=G-protein coupled receptor 183; AltName: Full=Epstein-Barr virus-induced G-protein coupled receptor 2; Short=EBI2; Short=EBV-induced G-protein coupled receptor 2; FUNCTION: Receptor for oxysterol 7-alpha,25-dihydroxycholesterol (7-alpha,25-OHC) and other related oxysterols. Binding of 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 throughG(s)-alpha or G(q)-alpha. Signals constitutively also via MAPK1/3 (ERK1/2). SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: Expressed abundantly in lymphoid tissues such as spleen and lymph node, and in B- and T-lymphocytes. Also highly expressed in lung, heart and gastrointestinal tract, and weakly expressed in the urogenital system and brain. INDUCTION: By Epstein-Barr virus (EBV). MISCELLANEOUS: GSK682753A (8-[(2E)-3-(4-chlorophenyl)prop-2- enoyl]-3-[(3,4-dichlorophenyl)methyl]-1-oxa-3,8- diazaspiro[4.5]decan-2-one), an inverse agonist, selectively inhibits the constitutive activity of GPR183 with high potency and efficacy (PubMed:21673108). SIMILARITY: Belongs to the G-protein coupled receptor 1 family. CAUTION: It is uncertain whether Met-1 or Met-5 is the initiator.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
