Protein Name: ATP-dependent RNA helicase A

UniprotKB/SwissProt ID: DHX9_HUMAN (Q08211)

Gene Name: DHX9

Synonyms: DDX9, LKP, NDH2

Organism: Homo sapiens (Human).

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. Positively regulates HIV-1 LTR-directed gene expression.

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Nucleus, nucleolus. Cytoplasm. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Can shuttle between nucleus and cytoplasm.
