我们已经分析了人类着丝粒染色质含有CENPA从HeLa细胞在培养中使用染色质IP,然后通过原子力显微镜测量和质谱。到目前为止,我们已经确定CENPA染色质结构在间期期间是独特组织的,并且具有与包装基因组的其余染色质根本不同的特征。我们计划在整个细胞周期中使用实时成像与AFM结合来扩展我们的分析,以解决CENP-A如何组装和保留,以及它如何参与异位位点的非着丝粒功能。我们已经发现CENP-A在细胞周期中改变其结构。这份手稿已提交出版。
英文摘要
We have analyzed human centromeric chromatin containing CENPA from HeLa cells in culture using Chromatin IP followed by atomic force microscopy measurements and mass spectrophotometry. Thus far, we have identified that the CENPA chromatin structure is uniquely organized during interphase, and has fundamentally different characteristics from the rest of the chromatin which packages the genome. We plan to extend our analysis using live imaging coupled with AFM across the cell cycle to address how CENP-A is assembled and retained, as well as how it participates in non-centromeric functions at ectopic loci. We have discovered that CENP-A changes its structure over the cell cycle. This manuscript has been submitted for publication.
