The linker of nucleoskeleton and cytoskeleton (LINC) complex is a protein complex across the nuclear envelope and has maintained its general assembly mode throughout evolution. SUN and KASH proteins, which are the major components of LINC complex, interact with each other in the nuclear lumen to transmit forces across the nuclear envelope and have diverse functions. However, research of LINC complex in budding yeast has been limited due to the lack of identification of a canonical KASH protein and a cytoskeleton factor. Here, we review recent findings that addressed these puzzles in budding yeast. We highlight the distinct assembly model of the telomere-associated LINC complex in budding yeast, which could be beneficial for identifying LINC variants in other eukaryotes.
核骨架与细胞骨架连接复合体(LINC复合体)是一种跨越核膜的蛋白质复合体,在整个进化过程中一直保持其总体组装模式。SUN蛋白和KASH蛋白是LINC复合体的主要组成部分,它们在核腔内相互作用,以传递跨越核膜的力,并具有多种功能。然而,由于缺乏典型的KASH蛋白和细胞骨架因子的鉴定,对芽殖酵母中LINC复合体的研究一直受到限制。在这里,我们回顾了最近在芽殖酵母中解决这些谜题的研究结果。我们强调了芽殖酵母中端粒相关LINC复合体独特的组装模式,这可能有助于识别其他真核生物中的LINC变体。
