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).
