Acetylation: a regulatory modification to rival phosphorylation?
TLDR
This review sets out what the authors know about the broader substrate specificity and regulation of acetylases and goes on to compare acetylation with the process of phosphorylation.Abstract:
The fact that histones are modified by acetylation has been known for almost 30 years. The recent identification of enzymes that regulate histone acetylation has revealed a broader use of this modification than was suspected previously. Acetylases are now known to modify a variety of proteins, including transcription factors, nuclear import factors and α–tubulin. Acetylation regulates many diverse functions, including DNA recognition, protein–protein interaction and protein stability. There is even a conserved structure, the bromodomain, that recognizes acetylated residues and may serve as a signalling domain. If you think all this sounds familiar, it should be. These are features characteristic of kinases. So, is acetylation a modification analogous to phosphorylation? This review sets out what we know about the broader substrate specificity and regulation of acetyl– ases and goes on to compare acetylation with the process of phosphorylation.read more

Lysine Acetylation Targets Protein Complexes and Co-Regulates Major Cellular Functions
Chunaram Choudhary,Chanchal Kumar,Florian Gnad,Michael L. Nielsen,Michael Rehman,Tobias C. Walther,Jesper V. Olsen,Matthias Mann +7 more
TL;DR: A proteomic-scale analysis of protein acetylation suggests that it is an important biological regulatory mechanism and the regulatory scope of lysine acetylations is broad and comparable with that of other major posttranslational modifications.

TL;DR: In this paper, the authors identify a histone demethylase conserved from S. pombe to human and reveal dynamic regulation of histone methylation by both histonemethylases and demethylases.

The many roles of histone deacetylases in development and physiology: Implications for disease and therapy
TL;DR: In this article, the expression of many HDAC isoforms in eukaryotic cells raises questions about their possible specificity or redundancy, and whether they control global or specific programs of gene expression.

Histone deacetylase inhibitors and the promise of epigenetic (and more) treatments for cancer
TL;DR: Investigating aspects of HDACi action both in vitro and in vivo will further improve the design of optimized clinical protocols and help to understand the role of histone deacetylases in tumorigenesis.

HDAC6 is a microtubule-associated deacetylase
Charlotte Hubbert,Amaris Guardiola,Rong Shao,Yoshiharu Kawaguchi,Akihiro Ito,Andrew B. Nixon,Minoru Yoshida,Xiao-Fan Wang,Tso-Pang Yao +8 more
TL;DR: The results show that HDAC6 is the tubulin deacetylase, and provide evidence that reversible acetylation regulates important biological processes beyond histone metabolism and gene transcription, including microtubule-dependent cell motility.

Histone acetylation in chromatin structure and transcription
TL;DR: The amino termini of histones extend from the nucleosomal core and are modified by acetyltransferases and deacetylases during the cell cycle, which may direct histone assembly and help regulate the unfolding and activity of genes.

TL;DR: It is demonstrated that p53 can be modified by acetylated both in vivo and in vitro, indicating a novel pathway for p53 activation and providing an example of an acetylation-mediated change in the function of a nonhistone regulatory protein.

The CBP co-activator is a histone acetyltransferase
TL;DR: It is shown that CBP has intrinsic HAT activity, and Targeting CBP-associated H AT activity to specific promoters may be a mechanism by which E1A acts as a transcriptional activator.

TL;DR: A role for histone deacetylase as a key regulator of eukaryotic transcription is supported by the predicted protein, which is very similar to the yeast transcriptional regulator Rpd3p.
