Web17 sep. 2024 · NuA4 is a highly conserved multisubunit histone acetyltransferase (HAT) complex responsible for the acetylation of nucleosomal histone H4 and H2A (and variants H2A.Z/X) through its KAT5 (Esa1/Tip60) catalytic subunit ().As the only essential HAT in yeast, NuA4 regulates through chromatin modification the expression of specific genes … Web17 nov. 2024 · Tight transcriptional control guaranteed by H2A.Z nucleosomes depends on the context provided by other histone variants or chromatin modifications, such as histone acetylation. The functional cooperation of SWR1-type remodelers with NuA4 histone acetyltransferase complexes, a recurring theme during evolution, is structurally …

Web23 mrt. 2004 · We link this complex structurally and genetically to the NuA4 histone acetyltransferase (HAT) and the Ino80-C chromatin remodeling complex. Results A Protein Complex (SWR1-Com) Associated with the Histone Variant H2A.Z H2A.Z is important for specifying euchromatic regions in the genome of S. cerevisiae ( Meneghini et al. 2003 ). Web1 apr. 2024 · Interestingly, data from our lab suggest that NuA4 may have functions in RNA splicing that are independent of H2A.Z deposition. Using directed genetic screens we … doctor robert werner hackettstown

Web25 jul. 2011 · Thus, H2A.Z was suggested to prevent expansion of silent chromatin into transcriptionally active euchromatin. Recent in vitro data suggest that SWR1 mediated deposition of H2A.Z depends on acetylation of H2A and H4 by NuA4 histone acetyltransferase (HAT) complexes . Web12 jul. 2024 · The NuA4 protein complex acetylates histones H4 and H2A to activate both transcription and DNA repair. We report the 3.1 Å-resolution cryo-electron microscopy structure of the central hub of NuA4 ...
