Alternate Names for VASA Antibody [Unconjugated]

  • DEAD (Asp-Glu-Ala-Asp) box polypeptide 4
  • DEAD box protein 4
  • EC 3.6.1

  • probable ATP-dependent RNA helicase DDX4
  • Vasa homolog
  • VASA
  • VASADEAD/H (Asp-Glu-Ala-Asp/His) box polypeptide 4


The VASA gene, originally identified in Drosophila, encodes a member of the DEAD box family of ATP-dependent RNA helicases. The expression of VASA in invertebrate and vertebrate species is restricted to germ cells and is required for germ cell formation. VASA is therefore a highly specific marker of germ cells (1-3).
