Structures of APC/C(Cdh1) with substrates identify Cdh1 and Apc10 as the D-box co-receptor.
(NATURE PUBLISHING GROUP, 2011-02-10)
The ubiquitylation of cell-cycle regulatory proteins by the large multimeric anaphase-promoting complex (APC/C) controls sister chromatid segregation and the exit from mitosis. Selection of APC/C targets is achieved through ...
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 ...
Architecture of the chromatin remodeler RSC and insights into its nucleosome engagement.
(ELIFE SCIENCES PUBLICATIONS LTD, 2019-12-30)
Eukaryotic DNA is packaged into nucleosome arrays, which are repositioned by chromatin remodeling complexes to control DNA accessibility. The Saccharomyces cerevisiae RSC (Remodeling the Structure of Chromatin) complex, a ...
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 ...
Cnn1 inhibits the interactions between the KMN complexes of the yeast kinetochore.
(NATURE PUBLISHING GROUP, 2012-05-06)
Kinetochores attach the replicated chromosomes to the mitotic spindle and orchestrate their transmission to the daughter cells. Kinetochore-spindle binding and chromosome segregation are mediated by the multi-copy KNL1(Spc105), ...
Nse5/6 is a negative regulator of the ATPase activity of the Smc5/6 complex.
(OXFORD UNIV PRESS, 2021-05-07)
The multi-component Smc5/6 complex plays a critical role in the resolution of recombination intermediates formed during mitosis and meiosis, and in the cellular response to replication stress. Using recombinant proteins, ...
Expression of Mitochondrial Cytochrome C Oxidase Chaperone Gene (COX20) Improves Tolerance to Weak Acid and Oxidative Stress during Yeast Fermentation.
(PUBLIC LIBRARY SCIENCE, 2015-10-01)
INTRODUCTION: Saccharomyces cerevisiae is the micro-organism of choice for the conversion of fermentable sugars released by the pre-treatment of lignocellulosic material into bioethanol. Pre-treatment of lignocellulosic ...
Structural basis of Ty3 retrotransposon integration at RNA Polymerase III-transcribed genes.
(NATURE PORTFOLIO, 2021-11-30)
Retrotransposons are endogenous elements that have the ability to mobilise their DNA between different locations in the host genome. The Ty3 retrotransposon integrates with an exquisite specificity in a narrow window ...
Redox requirements for ubiquitin-like urmylation of Ahp1, a 2-Cys peroxiredoxin from yeast.
(ELSEVIER, 2020-02-01)
The yeast peroxiredoxin Ahp1, like related anti-oxidant enzymes in other species, undergoes urmylation, a lysine-directed conjugation to ubiquitin-like modifier Urm1. Ahp1 assembles into a homodimer that detoxifies peroxides ...
