DDX21

DEAD (Asp-Glu-Ala-Asp) box helicase 21

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. Based on their distribution patterns, some members of this family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. This gene encodes a DEAD box protein, which is an antigen recognized by autoimmune antibodies from a patient with watermelon stomach disease. This protein unwinds double-stranded RNA, folds single-stranded RNA, and may play important roles in ribosomal RNA biogenesis, RNA editing, RNA transport, and general transcription.

Gene Name: DEAD (Asp-Glu-Ala-Asp) box helicase 21
Family/Subfamily: DEAD box protein
Synonyms: DDX21, DEAD box protein 21, Gu protein, GUA, GURDB, Gu-alpha, Nucleolar RNA helicase II, Nucleolar RNA helicase Gu, RH II/Gu, RNA helicase II/Gu alpha, Nucleolar RNA helicase 2, RH-II/GU, RH-II/GuA
Target Sequences: NM_004728 NP_004719.2 Q9NR30

DDX21 Antibody - Immunofluorescence staining of DDX21 in U251MG cells. Cells were fixed with 4% PFA, permeabilzed with 0.1% Triton X-100 in PBS, blocked with 10% serum, and incubated with rabbit anti-Human DDX21 polyclonal antibody (dilution ratio 1:200) at 4°C overnight. Then cells were stained with the Alexa Fluor 488-conjugated Goat Anti-rabbit IgG secondary antibody (green) and counterstained with DAPI (blue). Positive staining was localized to Nucleus.
