摘要
在真核细胞中,DNA 缠绕在组蛋白八聚体上,以压实基因组。虽然这种压实是细胞分裂过程中基因组精确分离所必需的,但它限制了一些细胞过程所必需的 DNA 蛋白相互作用。减数分裂是一种产生配子的特殊细胞分裂过程,在减数分裂过程中,DNA 与蛋白质之间的相互作用对组装减数分裂特异性染色体结构、减数分裂重组、染色体分离和转录调控至关重要。染色质重塑因子(CRs)在有丝分裂过程中促进 DNA 蛋白相互作用的作用已得到广泛认可,但它们如何促进减数分裂特异性过程却鲜为人知。在这篇综述中,我们总结了在各种模式系统中支持染色质重塑子在减数分裂中作用的实验证据,并提出了推进该领域研究的未来展望。
Role of ATP-dependent chromatin remodelers in meiosis.
In eukaryotic cells, DNA is wrapped around histone octamers to compact the genome. Although such compaction is required for the precise segregation of the genome during cell division, it restricts the DNA-protein interactions essential for several cellular processes. During meiosis, a specialized cell division process that produces gametes, several DNA-protein interactions are crucial for assembling meiosis-specific chromosome structures, meiotic recombination, chromosome segregation, and transcriptional regulation. The role of chromatin remodelers (CRs) in facilitating DNA-protein transactions during mitosis is well appreciated, whereas how they facilitate meiosis-specific processes is poorly understood. In this review, we summarize experimental evidence supporting the role of CRs in meiosis in various model systems and suggest future perspectives to advance the field.
期刊介绍:
Launched in 1985, Trends in Genetics swiftly established itself as a "must-read" for geneticists, offering concise, accessible articles covering a spectrum of topics from developmental biology to evolution. This reputation endures, making TiG a cherished resource in the genetic research community. While evolving with the field, the journal now embraces new areas like genomics, epigenetics, and computational genetics, alongside its continued coverage of traditional subjects such as transcriptional regulation, population genetics, and chromosome biology.
Despite expanding its scope, the core objective of TiG remains steadfast: to furnish researchers and students with high-quality, innovative reviews, commentaries, and discussions, fostering an appreciation for advances in genetic research. Each issue of TiG presents lively and up-to-date Reviews and Opinions, alongside shorter articles like Science & Society and Spotlight pieces. Invited from leading researchers, Reviews objectively chronicle recent developments, Opinions provide a forum for debate and hypothesis, and shorter articles explore the intersection of genetics with science and policy, as well as emerging ideas in the field. All articles undergo rigorous peer-review.
