- The underlying physics of all ferromagnetic behavior is the cooperative interaction between individual atomic magnetic moments that results in a macroscopic magnetization. In this work, we use extreme ultraviolet pulses ...
- Tfb6, a previously unidentified subunit of the general transcription factor TFIIH, facilitates dissociation of Ssl2 helicase after transcription initiation
[作者:Murakami, K; Gibbons, BJ; Davis, RE; Nagai, S; Liu, X; Robinson, PJJ; Wu, TH; Kaplan, CD; Kornberg, RD,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:4816-4821 , 文章类型: Article,,卷期:2012年109-13]
- General transcription factor TFIIH, previously described as a 10-subunit complex, is essential for transcription and DNA repair. An eleventh subunit now identified, termed Tfb6, exhibits 45% sequence similarity to human ...
- Structure of the ZU5-ZU5-UPA-DD tandem of ankyrin-B reveals interaction surfaces necessary for ankyrin function
