The influence of zCep85 and zNek2 on the early embryonic development of zebrafish

Abstract

zCep85是哺乳动物中心体结合蛋白Cep85在斑马鱼中的同源蛋白,其靠近C端的部分具有一个coil-coiled功能域,这是大部分中心体结合蛋白共有的结构。目前对zCep85的研究尚浅,本实验室早期报道显示,哺乳动物细胞中hCep85特异性地拮抗hNek2,使得细胞停滞于G2/M期。但是,我们对其在脊椎动物胚胎发育中的功能依然所知甚少。为了深入探究zCep85在发育中的作用,本课题以斑马鱼(Daniorerio)为动物模型从基因结构、表达谱、功能分析等方面研究了zCep85在胚胎发育中的作用。此外,也研究了zNek2在早期胚胎发育中的功能。 首先通过整胚原位杂交实验对zCep85的表达谱进...zCep85 is homologous of mammal centrosome binding protein Cep85 in zebrafish, which has a coil - coiled functional domain near the C-terminal of protein.At present,the research on zCep85 is not much. hCep85 can specifically antagonise hNek2 ,which acts as the role in making the cell cycle arrested of G2 / M phase. In this project, zebrafish (Danio rerio) can be looked as an animal model of gene st...学位:理学硕士院系专业:生命科学学院_生物化学与分子生物学学号:2162013115262
