ID:SARAF_HUMAN DESCRIPTION: RecName: Full=Store-operated calcium entry-associated regulatory factor; Short=SARAF; Short=SOCE-associated regulatory factor; AltName: Full=HBV X-transactivated gene 3 protein; AltName: Full=HBV XAg-transactivated protein 3; AltName: Full=Protein FOAP-7; AltName: Full=Transmembrane protein 66; Flags: Precursor; FUNCTION: Negative regulator of store-operated Ca(2+) entry (SOCE) involved in protecting cells from Ca(2+) overfilling. In response to cytosolic Ca(2+) elevation after endoplasmic reticulum Ca(2+) refilling, promotes a slow inactivation of STIM (STIM1 or STIM2)- dependent SOCE activity: possibly act by facilitating the deoligomerization of STIM to efficiently turn off ORAI when the endoplasmic reticulum lumen is filled with the appropriate Ca(2+) levels, and thus preventing the overload of the cell with excessive Ca(2+) ions. SUBUNIT: Interacts with STIM1. SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass type I membrane protein. Note=Translocates to the endoplasmic reticulum-plasma membrane (ER-PM) region in a STIM1-dependent manner following cytosolic Ca(2+) elevation. SUBCELLULAR LOCATION: Isoform 2: Endoplasmic reticulum membrane; Single-pass type I membrane protein. TISSUE SPECIFICITY: Highly expressed in macrophages. DOMAIN: The cytoplasmic C-terminal region mediates interaction with STIM1, while the N-terminal lumenal region mediates regulation of SOCE activity (PubMed:22464749). SIMILARITY: Belongs to the SARAF family. SEQUENCE CAUTION: Sequence=AAD44487.1; Type=Frameshift; Positions=28;
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.
