[HTML][HTML] Stepwise histone replacement by SWR1 requires dual activation with histone H2A. Z and canonical nucleosome

E Luk, A Ranjan, PC FitzGerald, G Mizuguchi, Y Huang… - Cell, 2010 - cell.com
Histone variant H2A.Z-containing nucleosomes are incorporated at most eukaryotic promoters.
This incorporation is mediated by the conserved SWR1 complex, which replaces histone …

[HTML][HTML] Nucleosome-free region dominates histone acetylation in targeting SWR1 to promoters for H2A. Z replacement

…, PC FitzGerald, D Wei, F Wang, Y Huang, E Luk… - Cell, 2013 - cell.com
The histone variant H2A.Z is a genome-wide signature of nucleosomes proximal to
eukaryotic regulatory DNA. Whereas the multisubunit chromatin remodeler SWR1 is known to …

[PDF][PDF] Chz1, a nuclear chaperone for histone H2AZ

E Luk, ND Vu, K Patteson, G Mizuguchi, WH Wu… - Molecular cell, 2007 - cell.com
The histone variant H2AZ marks nucleosomes flanking the promoters of most genes of
budding yeast. The incorporation of H2AZ into chromatin is dependent on the SWR1 complex, …

Swc2 is a widely conserved H2AZ-binding module essential for ATP-dependent histone exchange

WH Wu, S Alami, E Luk, CH Wu, S Sen… - Nature structural & …, 2005 - nature.com
The histone variant H2AZ is incorporated preferentially at specific locations in chromatin to
modulate chromosome functions. In Saccharomyces cerevisiae, deposition of histone H2AZ …

Copper chaperones: personal escorts for metal ions

LS Field, E Luk, VC Culotta - Journal of bioenergetics and biomembranes, 2002 - Springer
Copper serves as the essential cofactor for a number of enzymes involved in redox chemistry
and virtually all organisms must accumulate trace levels of copper in order to survive. …

[HTML][HTML] N terminus of Swr1 binds to histone H2AZ and provides a platform for subunit assembly in the chromatin remodeling complex

…, A Ladurner, G Mizuguchi, D Wei, H Xiao, E Luk… - Journal of biological …, 2009 - ASBMB
Variant histone H2AZ-containing nucleosomes are involved in the regulation of gene
expression. In Saccharomyces cerevisiae, chromatin deposition of histone H2AZ is mediated by …

Constitutive turnover of histone H2A. Z at yeast promoters requires the preinitiation complex

…, L Sun, C Au, D Labuz, Z Liu, M Chou, C Shen, E Luk - Elife, 2016 - elifesciences.org
10.7554/eLife.14243.001 The assembly of the preinitiation complex (PIC) occurs upstream
of the +1 nucleosome which, in yeast, obstructs the transcription start site and is frequently …

NMR structure of chaperone Chz1 complexed with histones H2A. Z-H2B

Z Zhou, H Feng, DF Hansen, H Kato, E Luk… - Nature structural & …, 2008 - nature.com
The NMR structure of budding yeast chaperone Chz1 complexed with histones H2A.Z-H2B
has been determined. Chz1 forms a long irregular chain capped by two short α-helices, and …

Manganese activation of superoxide dismutase 2 in Saccharomyces cerevisiae requires MTM1, a member of the mitochondrial carrier family

E Luk, M Carroll, M Baker… - Proceedings of the …, 2003 - National Acad Sciences
Manganese-containing superoxide dismutase (SOD2) plays a critical role in guarding against
mitochondrial oxidative stress and is essential for survival of many organisms. Despite the …

[HTML][HTML] Manganese activation of superoxide dismutase 2 in the mitochondria of Saccharomyces cerevisiae

E Luk, M Yang, LT Jensen, Y Bourbonnais… - Journal of Biological …, 2005 - ASBMB
Manganese-dependent superoxide dismutase 2 (SOD2) in the mitochondria plays a key
role in protection against oxidative stress. Here we probed the pathway by which SOD2 …
