ID:XPR1_HUMAN DESCRIPTION: RecName: Full=Xenotropic and polytropic retrovirus receptor 1; AltName: Full=Protein SYG1 homolog; AltName: Full=Xenotropic and polytropic murine leukemia virus receptor X3; Short=X-receptor; FUNCTION: May function in G-protein coupled signal transduction (By similarity). Potential receptor for xenotropic and polytropic murine leukemia retroviruses. SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein (Probable). TISSUE SPECIFICITY: Widely expressed. Detected in spleen, lymph node, thymus, leukocytes, bone marrow, heart, kidney, pancreas and skeletal muscle. DEVELOPMENTAL STAGE: Expressed in fetal liver. SIMILARITY: Belongs to the SYG1 (TC 2.A.94) family. SIMILARITY: Contains 1 EXS domain. SIMILARITY: Contains 1 SPX domain. CAUTION: It is unclear whether its ability to act as a receptor for xenotropic and polytropic murine leukemia retroviruses is relevant in vivo and whether such viruses can infect human.
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.
