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

Multiplex immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human testis tissue.
Panel A: Merged staining of anti-Vimentin (ab193555; red; Opal™690), anti-CYP11A1 (ab272494; cyan; Opal™520) and anti-DDX4 / MVH (ab270534; green; Opal™570) on human testis.
Panel B: Anti-CYP11A1 stained on Leydig cells.
Panel C: Anti-DDX4 / MVH stained on all spermatogenic cell types.
Panel D: Anti-Vimentin stained on Sertoli cells and fibroblasts.
Key protocol steps: The section was incubated in three rounds of staining: in the order of ab193555 (1:2000 dilution) and ab272494 (1:10000 dilution) for 30 mins, then ab270534 (1:2000 dlilution) for 10 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.
The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope.
DAPI was used as a nuclear counter stain. Opal Polymer HRP Ms + Rb was used as a secondary.
Antigen retrieval: Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins
