摘要 蛋白质精氨酸甲基转移酶 5 (Prmt5) 是一种 II 型精氨酸甲基转移酶,可对称地二甲基化核蛋白和细胞质蛋白中的精氨酸。 Prmt5 参与多种细胞过程,包括核糖体生物发生、细胞分化、生殖细胞发育和肿瘤发生。然而,prmt5 影响细胞过程的机制仍不清楚。在此,斑马鱼中prmt5的缺失导致由于生殖细胞数量减少、生殖细胞凋亡增加以及性腺无法分化为正常睾丸或卵巢而导致雄性不育表型的表达。此外,在 prmt5 缺失的斑马鱼的性腺中,生殖细胞特异性蛋白 Zili 和 Vasa 以及组蛋白 H3 (H3R8me2s) 和 H4 (H4R3me2s) 的精氨酸甲基化降低。这导致了几种 Piwi 通路蛋白的下调,包括 Zili 和 Vasa。此外,在prmt5缺失的斑马鱼的性腺中,与减数分裂、性腺发育和性分化相关的各种基因失调。我们的结果揭示了与 prmt5 相关的新机制,即 prmt5 显然通过催化种系特异性蛋白 Zili 和 Vasa 的精氨酸甲基化来控制脊椎动物的生殖细胞发育。摘要:Prmt5 显然通过催化种系特异性蛋白 Zili 和 Vasa 的精氨酸甲基化来控制生殖细胞发育。
ABSTRACT Protein arginine methyltransferase 5 (Prmt5), a type II arginine methyltransferase, symmetrically dimethylates arginine in nuclear and cytoplasmic proteins. Prmt5 is involved in a variety of cellular processes, including ribosome biogenesis, cellular differentiation, germ cell development and tumorigenesis. However, the mechanisms by which prmt5 influences cellular processes have remained unclear. Here, prmt5 loss in zebrafish led to the expression of an infertile male phenotype due to a reduction in germ cell number, an increase in germ cell apoptosis and the failure of gonads to differentiate into normal testes or ovaries. Moreover, arginine methylation of the germ cell-specific proteins Zili and Vasa, as well as histones H3 (H3R8me2s) and H4 (H4R3me2s), was reduced in the gonads of prmt5-null zebrafish. This resulted in the downregulation of several Piwi pathway proteins, including Zili, and Vasa. In addition, various genes related to meiosis, gonad development and sexual differentiation were dysregulated in the gonads of prmt5-null zebrafish. Our results revealed a novel mechanism associated with prmt5, i.e. prmt5 apparently controls germ cell development in vertebrates by catalyzing arginine methylation of the germline-specific proteins Zili and Vasa. Summary: Prmt5 apparently controls germ cell development by catalyzing arginine methylation of the germline-specific proteins Zili and Vasa.
