HDACs, including HDAC1, HDAC2, HDAC3, and HDAC8, are responsible for removing crotonylation modifications from histones (88). Although Japanese scientists first discovered palmitoylation modifications ...
在48 小时的观察期内,记录了胚胎干细胞的动态荧光变化,以供人工检查和统计分析。 K) 对照组和经 CHX/MG132 处理的胚胎干细胞的延时成像。箭头显示进入和退出 2C-like的方向(箭头)。比例尺,50 μm。L) 箱线图展示了有无药物处理情况下进入和退出2C-like的时间。
USP22与NP的互作机制?? 通过环己酰亚胺(CHX)追踪实验发现NP通过泛素-蛋白酶体途径降解。非选择性DUB抑制剂PR-619处理加速NP降解,而蛋白酶体抑制剂MG132可逆转此效应。利用DUB表达文库筛选发现USP22、USP49和USP50显著上调NP水平,但仅USP22与NP存在直接互作(免疫共 ...
The requirement of active proteasome was further demonstrated in U2OS cells transiently expressing PARP14 mutant deficient in ADP-ribosylhydrolase activity. Adding MG132 resulted in the loss of the ...
