ID:DHX9_HUMAN DESCRIPTION: RecName: Full=ATP-dependent RNA helicase A; Short=RHA; EC=3.6.4.13; AltName: Full=DEAH box protein 9; AltName: Full=Leukophysin; Short=LKP; AltName: Full=Nuclear DNA helicase II; Short=NDH II; FUNCTION: Unwinds double-stranded DNA and RNA in a 3' to 5' direction. Alteration of secondary structure may subsequently influence interactions with proteins or other nucleic acids. Functions as a transcriptional activator. Component of the CRD- mediated complex that promotes MYC mRNA stability. Involved with LARP6 in the stabilization of type I collagen mRNAs for CO1A1 and CO1A2. CATALYTIC ACTIVITY: ATP + H(2)O = ADP + phosphate. SUBUNIT: Interacts with ZIC2 (By similarity). Component of the coding region determinant (CRD)-mediated complex, composed of DHX9, HNRNPU, IGF2BP1, SYNCRIP and YBX1. Identified in a mRNP complex, at least composed of DHX9, DDX3X, ELAVL1, HNRNPU, IGF2BP1, ILF3, PABPC1, PCBP2, PTBP2, STAU1, STAU2, SYNCRIP and YBX1. Identified in a mRNP granule complex, at least composed of ACTB, ACTN4, DHX9, ERG, HNRNPA1, HNRNPA2B1, HNRNPAB, HNRNPD, HNRNPL, HNRNPR, HNRNPU, HSPA1, HSPA8, IGF2BP1, ILF2, ILF3, NCBP1, NCL, PABPC1, PABPC4, PABPN1, RPLP0, RPS3, RPS3A, RPS4X, RPS8, RPS9, SYNCRIP, TROVE2, YBX1 and untranslated mRNAs. Interacts with IGF2BP1. Binds MBD2, HRMT1L2/PRMT1, and RELA. May act to directly link BRCA1, CREBBP or SMN1 and the RNA polymerase II complex. Can also interact with XRCC5 and with TOP2A in an RNA dependent manner; these interactions may be indirect. Interaction with TOP2A is promoted by UBC9. Interacts with histone H2AFX and this requires phosphorylation of H2AFX on 'Ser-139'. Interacts with LARP6. INTERACTION: P19525:EIF2AK2; NbExp=2; IntAct=EBI-352022, EBI-640775; Q9UBU9:NXF1; NbExp=7; IntAct=EBI-352022, EBI-398874; Q99873:PRMT1; NbExp=2; IntAct=EBI-352022, EBI-78738; Q04206:RELA; NbExp=4; IntAct=EBI-352022, EBI-73886; SUBCELLULAR LOCATION: Nucleus, nucleolus. Cytoplasm. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Can shuttle between nucleus and cytoplasm. DOMAIN: The MTAD domain mediates interaction with the RNA polymerase II holoenzyme. The NTD domain is necessary and sufficient for nucleo-cytoplasmic shuttling and interaction with HRMT1L2 and SMN1. PTM: Methylated. HRMT1L2 mediated methylation of undefined Arg residues in the NTD is required for nuclear localization. PTM: May be phosphorylated by PRKDC/XRCC7. Phosphorylated upon DNA damage, probably by ATM or ATR. SIMILARITY: Belongs to the DEAD box helicase family. DEAH subfamily. SIMILARITY: Contains 2 DRBM (double-stranded RNA-binding) domains. SIMILARITY: Contains 1 helicase ATP-binding domain. SIMILARITY: Contains 1 helicase C-terminal domain.
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.
