减数分裂重组导致交换的形成,通过交换,在减数分裂前期I期间同源染色体之间交换遗传信息。变性是一个涉及许多蛋白质的复杂过程。参与重组的基因的改变可能导致不育。分子生物学研究提高了我们对重组蛋白和蛋白复合物的作用和机制的理解,其中一些蛋白和蛋白复合物在有丝分裂细胞和减数分裂细胞中具有功能。人类基因测序研究已经对其中一些基因进行了研究,并提供了在一些不育个体中观察到的表型的进一步信息。然而,需要进一步的研究来帮助阐明特定蛋白质的特定作用,并增加我们对这些蛋白质系统的理解。这篇综述将集中在我们目前的理解蛋白质参与减数分裂重组从基因组的角度,总结我们目前的理解已知的突变和单核苷酸多态性,可能会影响男性生育力通过改变减数分裂重组。
Meiotic recombination results in the formation of crossovers, by which genetic information is exchanged between homologous chromosomes during prophase I of meiosis. Recombination is a complex process involving many proteins. Alterations in the genes involved in recombination may result in infertility. Molecular studies have improved our understanding of the roles and mechanisms of the proteins and protein complexes involved in recombination, some of which have function in mitotic cells as well as meiotic cells. Human gene sequencing studies have been performed for some of these genes and have provided further information on the phenotypes observed in some infertile individuals. However, further studies are needed to help elucidate the particular role(s) of a given protein and to increase our understanding of these protein systems. This review will focus on our current understanding of proteins involved in meiotic recombination from a genomic perspective, summarizing our current understanding of known mutations and single nucleotide polymorphisms that may affect male fertility by altering meiotic recombination.
