ID:SSRB_HUMAN DESCRIPTION: RecName: Full=Translocon-associated protein subunit beta; Short=TRAP-beta; AltName: Full=Signal sequence receptor subunit beta; Short=SSR-beta; Flags: Precursor; FUNCTION: TRAP proteins are part of a complex whose function is to bind calcium to the ER membrane and thereby regulate the retention of ER resident proteins. SUBUNIT: Heterotetramer of TRAP-alpha, TRAP-beta, TRAP-delta and TRAP-gamma. Interacts with TMEM173/STING. SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass type I membrane protein. SIMILARITY: Belongs to the TRAP-beta family. SEQUENCE CAUTION: Sequence=CAH72631.1; Type=Erroneous gene model prediction; Sequence=CAH72632.1; Type=Erroneous gene model prediction;
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.
Pfam Domains: PF05753 - Translocon-associated protein beta (TRAPB)
SCOP Domains: 49309 - Transglutaminase, two C-terminal domains

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.
