A complete understanding of these indirect relationships between enzyme expression and histone modification is important for understanding regulation in the cell and in the development of drugs for so-called "epigenetic targets".
Such membrane technology may drastically simplify the process of sizing DNA molecules and mapping DNA modifications, which are critical for understanding gene regulation and the dynamics of cellular machinery — now a lengthy process that involves expensive bench-top instruments.
The characterization of these modifications is, however, vital for understanding the cellular mechanisms involved in disease.
Reviewer 2: Sandor Pongor - International Centre for Genetic Engineering and Biotechnology, Trieste, Italy There is mounting evidence in recent years that the study of post-translational modifications has important lessons for understanding diverse aspects of protein evolution.
Histone modification data were retrieved from human histone modification database (HHMD, http://202.97.205.78/hhmd/index.jsp) [ 32] which contains useful histone modifications information from experimental data that is essential for understanding the modifications at a systematic level (Additional file 2: Table S2).
The position of the IIIa N-terminus and its low tolerance for modification provide new clues for understanding the role of this minor coat protein in Ad capsid assembly and disassembly.
In summary, our finding that PABP1 is subject to complex and dynamic post-translational modification provides a framework for understanding how multiple interactions with this key regulator of protein synthesis may be regulated to co-ordinate its numerous roles.
Knowledge of protein domains that function as the biological effectors for diverse post-translational modifications of histones is critical for understanding how nuclear and epigenetic programs are established.
In total, these data emphasize the importance of structural context when considering the effects of protein post-translational modifications and provide a basis for understanding situations in which phosphorylation and OGlcNAcylation may be opposing (e.g., yin-yang) versus complementary in their effects, both of which have been described in numerous biological contexts.
The application of ChIP-Seq to histone modification study has proved very useful for understanding the genomic landscape of histone modifications (Barski et al., 2007; Mikkelsen et al., 2007).
Electrochemical methods are good tools for understanding the modification of light-emitting properties of QD films by electron injection or ionic adsorption, for both fundamental research and technical applications.
