| Main function of each fusion partner protein. (from UniProt) |
| Hgene | Tgene |
| CPB1 | DDX21 |
| RNA helicase that acts as a sensor of thetranscriptional status of both RNA polymerase (Pol) I and II:promotes ribosomal RNA (rRNA) processing and transcription frompolymerase II (Pol II) (PubMed:25470060). Binds various RNAs, suchas rRNAs, snoRNAs, 7SK and, at lower extent, mRNAs(PubMed:25470060). In the nucleolus, localizes to rDNA locus,where it directly binds rRNAs and snoRNAs, and promotes rRNAtranscription, processing and modification. Required for rRNA 2'-O-methylation, possibly by promoting the recruitment of late-acting snoRNAs SNORD56 and SNORD58 with pre-ribosomal complexes(PubMed:25470060, PubMed:25477391). In the nucleoplasm, binds 7SKRNA and is recruited to the promoters of Pol II-transcribed genes:acts by facilitating the release of P-TEFb from inhibitory 7SKsnRNP in a manner that is dependent on its helicase activity,thereby promoting transcription of its target genes(PubMed:25470060). Functions as cofactor for JUN-activatedtranscription: required for phosphorylation of JUN at 'Ser-77'(PubMed:11823437, PubMed:25260534). Can unwind double-stranded RNA(helicase) and can fold or introduce a secondary structure to asingle-stranded RNA (foldase) (PubMed:9461305). Involved in rRNAprocessing (PubMed:14559904, PubMed:18180292). May bind tospecific miRNA hairpins (PubMed:28431233).{ECO:0000269|PubMed:11823437, ECO:0000269|PubMed:14559904,ECO:0000269|PubMed:18180292, ECO:0000269|PubMed:25260534,ECO:0000269|PubMed:25470060, ECO:0000269|PubMed:25477391,ECO:0000269|PubMed:28431233, ECO:0000269|PubMed:9461305}. |
| 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. |
