Protein Structures |
| PDB and CIF files of the predicted protein structures * Here we show the 3D structure of the proteins using Mol*. AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Model confidence is shown from the pLDDT values per residue. pLDDT corresponds to the model’s prediction of its score on the local Distance Difference Test. It is a measure of local accuracy (from AlphfaFold website). To color code individual residues, we transformed individual PDB files into CIF format. |

| CCND2 | 17873913 | Human and mouse cyclin D2 splice variants: transforming activity and subcellular localization. | We have previously reported the identification of a novel 17 kDa truncated isoform of the cyclin D2 activated in 13% of the leukemias induced by the Graffi murine leukemia retrovirus. Retroviral integration in the Gris1 locus causes an alternative splicing of the mouse cyclin D2 gene and expression of a truncated protein of 159 amino acids that is detected at high levels in the Gris1 tumors and also in normal mouse tissues mainly the brain and ovaries. A truncated form of the cyclin D2 was also found in human. We show here that both mouse- and human-truncated cyclin D2 are able to transform primary mouse embryo fibroblasts (MEF) when co-expressed with an activated Ras protein. The truncated cyclin D2 localizes only to the cytoplasm of transfected cells. It has retained the ability to interact with cyclin-dependent kinases (CDKs), although it is a poor catalyst of pRb phosphorylation. Interestingly, the presence of a similar, alternatively spliced cyclin D2 mRNA was also detected in some human brain tumors. | D002471 | Cell Transformation, Neoplastic |
