Redox Signaling by the RNA Polymerase III TFIIB-Related Factor Brf2.
(CELL PRESS, 2015-12-03)
TFIIB-related factor 2 (Brf2) is a member of the family of TFIIB-like core transcription factors. Brf2 recruits RNA polymerase (Pol) III to type III gene-external promoters, including the U6 spliceosomal RNA and selenocysteine ...
Structure of human RNA polymerase III.
(NATURE RESEARCH, 2020-12-17)
In eukaryotes, RNA Polymerase (Pol) III is specialized for the transcription of tRNAs and other short, untranslated RNAs. Pol III is a determinant of cellular growth and lifespan across eukaryotes. Upregulation of Pol III ...
Human Condensin I and II Drive Extensive ATP-Dependent Compaction of Nucleosome-Bound DNA.
(CELL PRESS, 2020-07-02)
Structural maintenance of chromosomes (SMC) complexes are essential for genome organization from bacteria to humans, but their mechanisms of action remain poorly understood. Here, we characterize human SMC complexes condensin ...
Structural basis of RNA polymerase III transcription initiation.
(NATURE PORTFOLIO, 2018-01-17)
RNA polymerase (Pol) III transcribes essential non-coding RNAs, including the entire pool of transfer RNAs, the 5S ribosomal RNA and the U6 spliceosomal RNA, and is often deregulated in cancer cells. The initiation of gene ...
Molecular mechanisms of Bdp1 in TFIIIB assembly and RNA polymerase III transcription initiation.
(NATURE PUBLISHING GROUP, 2017-07-25)
Initiation of gene transcription by RNA polymerase (Pol) III requires the activity of TFIIIB, a complex formed by Brf1 (or Brf2), TBP (TATA-binding protein), and Bdp1. TFIIIB is required for recruitment of Pol III and to ...
