ID:BAP31_HUMAN DESCRIPTION: RecName: Full=B-cell receptor-associated protein 31; Short=BCR-associated protein 31; Short=Bap31; AltName: Full=6C6-AG tumor-associated antigen; AltName: Full=Protein CDM; AltName: Full=p28; FUNCTION: May play a role in anterograde transport of membrane proteins from the endoplasmic reticulum to the Golgi. May be involved in CASP8-mediated apoptosis. SUBUNIT: Homodimer and heterodimer with BCAP29. Binds CASP8 (isoform 9) as a complex containing BCAP31, BCAP29, BCL2 and/or BCL2L1. Interacts with VAMP3, VAMP1 and membrane IgD immunoglobulins. May interact with ACTG1 and non-muscle myosin II. Interacts with PTPLB. INTERACTION: P10415:BCL2; NbExp=2; IntAct=EBI-77683, EBI-77694; Q14790:CASP8; NbExp=3; IntAct=EBI-77683, EBI-78060; P13569:CFTR; NbExp=3; IntAct=EBI-77683, EBI-349854; Q9BUN8:DERL1; NbExp=3; IntAct=EBI-77683, EBI-398977; Q9Y3D6:FIS1; NbExp=8; IntAct=EBI-77683, EBI-3385283; Q6Y1H2:PTPLB; NbExp=4; IntAct=EBI-77683, EBI-530257; P60468:SEC61B; NbExp=7; IntAct=EBI-77683, EBI-1788819; Q15629:TRAM1; NbExp=5; IntAct=EBI-77683, EBI-1788852; SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass membrane protein. Endoplasmic reticulum-Golgi intermediate compartment membrane; Multi-pass membrane protein. Note=May shuttle between the ER and the intermediate compartment/cis-Golgi complex. TISSUE SPECIFICITY: Ubiquitous. PTM: Cleaved by CASP8 and other caspases. DISEASE: Note=BCAP31 is deleted in the chromosome Xq28 deletion syndrome which involves BCAP31 and the and the promoter region of ABCD1. SIMILARITY: Belongs to the BCAP29/BCAP31 family.
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.

Side
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.
