ID:RBBP6_HUMAN DESCRIPTION: RecName: Full=E3 ubiquitin-protein ligase RBBP6; EC=6.3.2.-; AltName: Full=Proliferation potential-related protein; AltName: Full=Protein P2P-R; AltName: Full=Retinoblastoma-binding Q protein 1; Short=RBQ-1; AltName: Full=Retinoblastoma-binding protein 6; AltName: Full=p53-associated cellular protein of testis; FUNCTION: E3 ubiquitin-protein ligase which promotes ubiquitination of YBX1, leading to its degradation by the proteasome. May play a role as a scaffold protein to promote the assembly of the p53/TP53-MDM2 complex, resulting in increase of MDM2-mediated ubiquitination and degradation of p53/TP53; may function as negative regulator of p53/TP53, leading to both apoptosis and cell growth. PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Interacts with p53/TP53 and RB1 (By similarity). Interacts also with MDM2 and YBX1. Interacts with NEK6. INTERACTION: Q16629:SRSF7; NbExp=3; IntAct=EBI-2117026, EBI-398885; SUBCELLULAR LOCATION: Nucleus, nucleolus. Chromosome. Cytoplasm, cytoskeleton, centrosome. Note=Colocalizes with mitotic chromosomes. Co-localizes with NEK6 in the centrosome. TISSUE SPECIFICITY: Highly expressed in the placenta and testis. Expressed at lower levels in the brain, heart, kidney, liver and lung. Overexpressed in esophageal cancer. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. Phosphorylated by NEK6. SIMILARITY: Contains 1 CCHC-type zinc finger. SIMILARITY: Contains 1 DWNN domain. SIMILARITY: Contains 1 RING-type zinc finger. SEQUENCE CAUTION: Sequence=AAG43155.1; Type=Miscellaneous discrepancy; Note=Intron retention; Sequence=AAH63524.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence. Potential poly-A sequence; Sequence=AAL05625.1; Type=Frameshift; Positions=198; Sequence=AAL68925.1; Type=Miscellaneous discrepancy; Note=Intron retention; Sequence=BAB15600.1; Type=Erroneous initiation; Sequence=CAA59445.1; Type=Frameshift; Positions=198, 1048, 1098;
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.
