a putative ATP-dependent RNA helicase. A proliferation-associated nuclear antigen, specifically reacting with the simian virus 40 tumor antigen. The rate of ATP hydrolysis is highly stimulated by single-stranded RNA. Belongs to the DEAD box helicase family. DDX5/DDX17 subfamily. DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases. They are implicated in a number of cellular processes involving alteration of RNA secondary structure, such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly.

Biological Process: alternative nuclear mRNA splicing, via spliceosome; androgen receptor signaling pathway; BMP signaling pathway; epithelial to mesenchymal transition; estrogen receptor signaling pathway; mRNA transcription; myoblast differentiation; negative regulation of transcription from RNA polymerase II promoter; nuclear mRNA splicing, via spliceosome; positive regulation of DNA damage response, signal transduction by p53 class mediator; positive regulation of estrogen receptor signaling pathway; positive regulation of transcription from RNA polymerase II promoter; regulation of alternative nuclear mRNA splicing, via spliceosome; regulation of osteoblast differentiation; regulation of transcription from RNA polymerase II promoter; RNA secondary structure unwinding
