機能
Probable ATP-dependent RNA helicase required during spermatogenesis (PubMed:10920202, PubMed:21034600). Required to repress transposable elements and preventing their mobilization, which is essential for the germline integrity. Acts via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governs the methylation and subsequent repression of transposons. Involved in the secondary piRNAs metabolic process, the production of piRNAs in fetal male germ cells through a ping-pong amplification cycle. -
組織特異性
Expressed only in ovary and testis. Expressed in migratory primordial germ cells in the region of the gonadal ridge in both sexes. -
配列類似性
Belongs to the DEAD box helicase family. DDX4/VASA subfamily.
Contains 1 helicase ATP-binding domain.
Contains 1 helicase C-terminal domain. -
細胞内局在
Cytoplasm. Cytoplasm, perinuclear region. Component of the meiotic nuage, also named P granule, a germ-cell-specific organelle required to repress transposon activity during meiosis. - Information by UniProt

Immunocytochemistry/ Immunofluorescence - Anti-DDX4 / MVH antibody (ab13840)This image is courtesy of an Abreview submitted by Mai Sarrajab13840 at 1/1000 staining germ cells of the embryonic mouse testis by ICC/IF. Cells were PFA fixed and permeabilized in 1% Triton X in PBS prior to blocking in 5% serum for 2 hours at 20°C. An Alexa Fluor® 488 conjugated goat anti-rabbit antibody was used as the secondary.

The tissue was blocked with both BSA and serum and fixed prior to incubation with the antibody for 3 hours at room temperature. A biotinylated secondary antibody was used (Vectastain Elite).
Please note Bouin's fluid was used as the fixative in this experiment.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-DDX4 / MVH antibody (ab13840)IHC image of DDX4/MVH staining in human testis formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab13840, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
