| Main function of each fusion partner protein. (from UniProt) |
| Hgene | Tgene |
| PTBP2 | PRKACB |
| FUNCTION: RNA-binding protein which binds to intronic polypyrimidine tracts and mediates negative regulation of exons splicing. May antagonize in a tissue-specific manner the ability of NOVA1 to activate exon selection. In addition to its function in pre-mRNA splicing, plays also a role in the regulation of translation. {ECO:0000250|UniProtKB:Q91Z31, ECO:0000269|PubMed:11003644, ECO:0000269|PubMed:12667457}.; FUNCTION: [Isoform 5]: Reduced affinity for RNA. {ECO:0000269|PubMed:12213192}. | FUNCTION: Mediates cAMP-dependent signaling triggered by receptor binding to GPCRs (PubMed:12420224, PubMed:21423175, PubMed:31112131). PKA activation regulates diverse cellular processes such as cell proliferation, the cell cycle, differentiation and regulation of microtubule dynamics, chromatin condensation and decondensation, nuclear envelope disassembly and reassembly, as well as regulation of intracellular transport mechanisms and ion flux (PubMed:12420224, PubMed:21423175). Regulates the abundance of compartmentalized pools of its regulatory subunits through phosphorylation of PJA2 which binds and ubiquitinates these subunits, leading to their subsequent proteolysis (PubMed:12420224, PubMed:21423175). Phosphorylates GPKOW which regulates its ability to bind RNA (PubMed:21880142). Acts as a negative regulator of mTORC1 by mediating phosphorylation of RPTOR (PubMed:31112131). {ECO:0000269|PubMed:12420224, ECO:0000269|PubMed:21423175, ECO:0000269|PubMed:21880142, ECO:0000269|PubMed:31112131}. |
| Retention analysis result of each fusion partner protein across 39 protein features of UniProt such as six molecule processing features, 13 region features, four site features, six amino acid modification features, two natural variation features, five experimental info features, and 3 secondary structure features. Here, because of limited space for viewing, we only show the protein feature retention information belong to the 13 regional features. All retention annotation result can be downloaded at * Minus value of BPloci means that the break pointn is located before the CDS. |

Kinase Fusion Protein Structures |
| CIF files of the predicted kinase fusion proteins * Here we show the 3D structure of the fusion 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. |
