蛋白质精氨酸甲基化是由蛋白质精氨酸甲基转移酶(PRMTs)催化的翻译后修饰,在许多生物学过程中起着重要作用。迄今为止,在哺乳动物中已经鉴定出9个PRMT家族成员,即PRMT 1、2、3、4、5、6、7、8和9。其中,PRMT 7是一种III型PRMT,仅能催化单甲基精氨酸的形成,在多种干细胞中起着关键作用。据报道,PRMT 7与胚胎干细胞、诱导多能干细胞、肌肉干细胞和人类癌症干细胞密切相关。PRMT7缺陷或突变导致小鼠和人类严重的发育迟缓,这可能是由于其在干细胞中的关键功能。在这里,我们调查和总结了PRMT7在小鼠和人类干细胞和发育中的研究,并在此提供了潜在的分子机制的讨论。此外,我们还讨论了PRMT7在癌症,脂肪形成,男性生殖,细胞应激和细胞衰老中的作用,以及PRMT7相关研究的未来前景。总体而言,PRMT7介导干细胞的增殖和分化。PRMT7的缺陷或突变导致发育迟缓,包括骨骼肌、骨、脂肪组织、神经元和男性生殖的缺陷。更好地了解PRMT7在干细胞和发育中的作用以及潜在的机制将为PRMT7和干细胞的深入研究及其在生命科学和医学中的应用提供策略。
Protein arginine methylation is a posttranslational modification catalyzed by protein arginine methyltransferases (PRMTs), which play critical roles in many biological processes. To date, nine PRMT family members, namely, PRMT1, 2, 3, 4, 5, 6, 7, 8, and 9, have been identified in mammals. Among them, PRMT7 is a type III PRMT that can only catalyze the formation of monomethylarginine and plays pivotal roles in several kinds of stem cells. It has been reported that PRMT7 is closely associated with embryonic stem cells, induced pluripotent stem cells, muscle stem cells, and human cancer stem cells. PRMT7 deficiency or mutation led to severe developmental delay in mice and humans, which is possibly due to its crucial functions in stem cells. Here, we surveyed and summarized the studies on PRMT7 in stem cells and development in mice and humans and herein provide a discussion of the underlying molecular mechanisms. Furthermore, we also discuss the roles of PRMT7 in cancer, adipogenesis, male reproduction, cellular stress, and cellular senescence, as well as the future perspectives of PRMT7-related studies. Overall, PRMT7 mediates the proliferation and differentiation of stem cells. Deficiency or mutation of PRMT7 causes developmental delay, including defects in skeletal muscle, bone, adipose tissues, neuron, and male reproduction. A better understanding of the roles of PRMT7 in stem cells and development as well as the underlying mechanisms will provide information for the development of strategies for in-depth research of PRMT7 and stem cells as well as their applications in life sciences and medicine.
