|October 14, 2008
Summary
Post translational modifications (PTMs) of histones are key to epigenetic regulation. Proteomics now allows detailed study of histone PTMs, their locations, combinations, and interactions, advancing our understanding of transcription.
Area of Science:
- Molecular Biology
- Epigenetics
- Proteomics
Background:
- Post translational modifications (PTMs) of histones are crucial for epigenetic regulation and gene transcription.
- Genomic methods have correlated some histone PTMs with transcriptional states, but a comprehensive understanding is lacking.
Purpose of the Study:
- To highlight recent advancements in proteomics for studying histone PTMs.
- To emphasize the need for integrated proteomic and genomic approaches to understand the functional significance of histone PTM combinations.
Main Methods:
- Utilizing mass spectrometry to identify the complete set of histone PTMs.
- Characterizing residue-specific locations, co-existing PTM combinations, and interacting proteins.
Main Results:
- Proteomics enables detailed analysis of the full histone PTM landscape.
- Identification of specific PTMs, their locations, combinations, and associated proteins is now possible.
Conclusions:
- Advancements in proteomics provide unprecedented insights into histone modifications.
- Future research should integrate proteomic and genomic data to elucidate the mechanisms by which histone PTMs regulate transcription.

02:32Histone Modification
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone deacetylase,...

01:12The Nucleosome Core Particle
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their primary aim is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. On the other hand, they must allow polymerase enzymes to access histone-bound DNA during...

01:33Proteomics
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...

02:54Nucleosome Remodeling
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.
