General annotation (Comments)
| Function | ATP-dependent RNA helicase. Binds to partially double-stranded RNAs (dsRNAs) in order to unwind RNA secondary structures. Unwinding is promoted in the presence of single-strand binding proteins. Mediates also RNA duplex formation thereby displacing the single-strand RNA binding protein. ATP and ADP modulate its activity: ATP binding and hydrolysis by DDX42 triggers RNA strand separation, whereas the ADP-bound form of the protein triggers annealing of complementary RNA strands. Involved in the survival of cells by interacting with TP53BP2 and thereby counteracting the apoptosis-stimulating activity of TP53BP2. Relocalizes TP53BP2 to the cytoplasm. Ref.10 Ref.12 |
| Catalytic activity | ATP + H2O = ADP + phosphate. |
| Subunit structure | Component of splicing factor SF3B which is composed of at least eight subunits; SF3B1/SAP155/SF3B155, SF3B2/SAP145/SF3B155, SF3B3/SAP130/SF3B130, SF3B4/SAP49/SF3B49, SF3B14A, PHF5A/SF3B14B, SF3B10 and SF3B125. Interacts (via the C-terminus) with TP53BP2; the interaction is not inhibitied by TP53BP2 ubiquitination and is independent of p53/TP53. Ref.8 Ref.12 |
| Subcellular location | Cytoplasm. Nucleus speckle. Nucleus › Cajal body. Note: Isoform 2 is present in Cajal bodies (CBs) and nuclear speckles. Ref.8 Ref.10 Ref.12 |
| Tissue specificity | Expressed in several cell lines (at protein level). Expressed in liver, lung, tonsil, thymus, muscle and pancreatic islets. Ref.1 Ref.10 |
| Sequence similarities | Belongs to the DEAD box helicase family. DDX42 subfamily. Contains 1 helicase ATP-binding domain. Contains 1 helicase C-terminal domain. |
| Sequence caution | The sequence AAC32396.1 differs from that shown. Reason: Frameshift at position 818. |
