本课题组主要以裂殖酵母为模式生物,采用的实验方法和技术涉及遗传学、细胞生物学及分子生物学手段。
研究兴趣主要包括三个方面:

1. 纺锤体组装检验点在调控有丝分裂染色体精确分配中的功能研究。
我们最近的研究发现,核仁蛋白Dnt1可以结合到APC/C复合体 (anaphase-promoting complex /cyclosome)上,限制纺锤体检验点蛋白复合体(mitotic checkpoint complex, MCC)与APC/C的过多结合。这样可以确保在纺锤体检验点失活时,细胞可以更有效地起始有丝分裂后期,完成细胞分裂;

2. 细胞极性生长调控机制研究。
我们最近的研究发现,裂殖酵母中的泛素连接酶(E3 ubiquitin ligase) Dma1除了定位在纺锤体极SPB处外,还会定位在细胞的极性生长的末端。当DNA复制或损伤检验点激活时,Dma1会泛素化修饰极性生长因子Tip1,这一修饰会抑制Tip1招募Tea4等极性生长因子,使细胞的极性生长停滞,有利于细胞在应对DNA复制压力时的存活;

3. 异染色质形成的表观遗传调控机制研究。
真核细胞的染色质可以分为常染色质和异染色质。裂殖酵母中的异染色质形成需要RNAi依赖的和RNAi非依赖的机制。我们最近的研究发现,分子伴侣蛋白Hsp90与 RNAi依赖的异染色质形成机制中RITS复合物存在相互作用,参与促进RITS复合物以及其上游的ARC复合物的组装。Hsp90还直接影响基因转录沉默复合物SHREC的组装。而在端粒区,Hsp90则影响Shelterin复合物对于CLRC以及SHREC复合物的招募。这一机制在高等真核生物包括人类细胞中可能也是保守的。

Taking advantage of the extensive technical amenability of the fission yeast schizosaccharomyces pombe, our research group employs multi-disciplinary approaches, such as genetics , cell biology and molecular biology, to dissect the detailed mechanisms how the positive and negative regulators control faithful chromosome segregation, cell polar growth and heterochromatin formation in eukaryotes.
Major interests of our ongoing research focus on: (1) the molecular mechanisms coordinating timely spindle assembly checkpoint (SAC) silencing with chromosome segregation fidelity at anaphase; (2) the molecular mechanisms coordinating cell cycle with cell polar growth; (3) the molecular mechanisms involved in the epigenetic regulation of heterochromatin formation.
