Abstract

The nuclear lamina (NL) is thought to aid in the spatial organization of interphase chromosomes by providing an anchoring platform for hundreds of large genomic regions named lamina associated domains (LADs). Recently, a new live-cell imaging approach demonstrated directly that LAD-NL interactions are dynamic and in part stochastic. Here we discuss implications of these new findings and introduce Lamin A and BAF as potential modulators of stochastic LAD positioning.

摘要

核纤层(NL)被认为通过为数百个名为核纤层相关结构域(LADs)的大型基因组区域提供锚定平台,来辅助间期染色体的空间组织。最近,一种新的活细胞成像方法直接证明了LAD-NL相互作用是动态的,且部分是随机的。在此,我们讨论这些新发现的意义,并介绍核纤层蛋白A和BAF作为随机LAD定位的潜在调节因子。
