During the early meiotic prophase, connections are established between chromosomes and cytoplasmic motors via a nuclear envelope bridge, known as a LINC (linker of nucleoskeleton and cytoskeleton) complex. These widely conserved links can promote both chromosome and nuclear motions. Studies in diverse organisms have illuminated the molecular architecture of these connections, but important questions remain regarding how they contribute to meiotic processes. Here, we summarize the current knowledge in the field, outline the challenges in studying these chromosome dynamics, and highlight distinctive features that have been characterized in major model systems.
在减数分裂前期早期,通过核膜桥(称为 LINC 复合物,核骨架和细胞骨架的连接物),在染色体和细胞质马达之间建立连接。这些广泛保守的连接可以促进染色体和核的运动。不同生物的研究阐明了这些连接的分子结构,但对于它们如何促进减数分裂过程,仍存在重要问题。在这里,我们总结了该领域的现有知识,概述了研究这些染色体动力学的挑战,并强调了在主要模型系统中已被描述的独特特征。
