有性生殖的后生动物在发育过程中建立了一个细胞谱系,最终致力于配子的产生。在多种动物中的工作表明,一组保守的分子决定因素在种系维持和功能中发挥作用。这些基因中最普遍的是vasa和vasa样DEAD盒RNA解旋酶基因。然而,最近的证据表明,vasa基因也在其他细胞类型中发挥作用,与生殖细胞不同。在这里,我们评估我们目前的理解vasa的功能及其在发展过程中的调节,解决vasa的多能细胞中的新兴作用。我们还探讨了该基因的氨基末端结构域的进化多样性,以及这如何影响vasa与nuage样核周结构的关联。
Sexually reproducing metazoans establish a cell lineage during development that is ultimately dedicated to gamete production. Work in a variety of animals suggests that a group of conserved molecular determinants function in this germ line maintenance and function. The most universal of these genes are vasa and vasa-like DEAD box RNA helicase genes. However, recent evidence indicates that vasa genes also function in other cell types, distinct from the germ line. Here we evaluate our current understanding of vasa function and its regulation during development, addressing vasa’s emerging role in multipotent cells. We also explore the evolutionary diversification of the amino-terminal domain of this gene and how this impacts the association of vasa with nuage-like perinuclear structures.
