ID:BCL9_HUMAN DESCRIPTION: RecName: Full=B-cell CLL/lymphoma 9 protein; Short=B-cell lymphoma 9 protein; Short=Bcl-9; AltName: Full=Protein legless homolog; FUNCTION: Involved in signal transduction through the Wnt pathway. Promotes beta-catenin's transcriptional activity (By similarity). SUBUNIT: Binds to beta-catenin (CTNNB1), PYGO1 and PYGO2. INTERACTION: P18824:arm (xeno); NbExp=3; IntAct=EBI-533127, EBI-216128; Q6P1J9:CDC73; NbExp=2; IntAct=EBI-533127, EBI-930143; P35222:CTNNB1; NbExp=2; IntAct=EBI-533127, EBI-491549; Q9V9W8:pygo (xeno); NbExp=3; IntAct=EBI-533127, EBI-152653; Q9Y3Y4:PYGO1; NbExp=7; IntAct=EBI-533127, EBI-3397474; SUBCELLULAR LOCATION: Nucleus (By similarity). TISSUE SPECIFICITY: Detected at low levels in thymus, prostate, testis, ovary and small intestine, and at lower levels in spleen, colon and blood. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. DISEASE: Note=A chromosomal aberration involving BCL9 is found in a patient with precusor B-cell acute lymphoblastic leukemia (ALL). Translocation t(1;14)(q21;q32). This translocation leaves the coding region intact, but may have pathogenic effects due to alterations in the expression level of BCL9. Several cases of translocations within the 3'-UTR of BCL9 have been found in B-cell malignancies. SIMILARITY: Belongs to the BCL9 family. CAUTION: It is uncertain whether Met-1 or Met-27 is the initiator. SEQUENCE CAUTION: Sequence=CAA73942.1; Type=Frameshift; Positions=1391; WEB RESOURCE: Name=Atlas of Genetics and Cytogenetics in Oncology and Haematology; URL="http://atlasgeneticsoncology.org/Genes/BCL9ID466.html";
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.
