Since 14 types of amino acids are potentially reactive (Xu et al. 2003), this method boasts considerably higher structural resolution than residue-specific techniques (such as lysine modification), which provide sparse sampling of the protein surface.
The ability to fragment proteins in the mass spectrometer enables identification of the positions of post-translational modifications, which provides information about disease processes.
In addition to the various classes of transcription factors, the transcriptional control of gene expression also depends on the state of histone modifications, which provides a dynamic control of chromatin activity.
It was found that NFG1CG4-tag sequence, FLAG®-GlyCys(Gly)4, effectively worked as a new N-terminal tag for site-specific chemical modifications, which provided an alternative to existing methods for N-terminal conjugation using different tag sequences [ 27, 28].
The light-emitting properties can be easily tuned from blue light-emitting to yellow light-emitting fluorescence by varying the nature of the heterocycle or by simple modification of structures, which provides a new strategy for the design of novel fluorescent switches.
Similar mortgage principal reductions have been supported by the International Monetary Fund and are encouraged in the government's Home Affordable Modification Program (HAMP), which provides monetary incentives to lenders for each dollar in principal reduced.
In summary, this study uncovered a novel unexpected function of alkylating agents targeting cancer-specific histone modification (H3K18 hypoacetylation), which provides a rationale for the combination with HDAC inhibitors to potentiate each anti-tumor activity against intractable malignancies by epigenetic means, as exemplified here in MCL.
Here we propose that co-transcriptional recruitment of splicing factor is modulated by histone modifications and Pol II processivity, which provides a link between chromatin modifications, transcription and splicing.
The photophysical properties of these compounds can be easily tuned by varying the electronic properties of the substituents or by simple modification of the molecular structure, which provides a new strategy for the design of novel fluorescent diarylethene systems to be used as switches.
At the same time, this study shows that the water resistance coefficient of MOC is concerned with the balance of hydration and hydrolysis reactions which provides two main modification approaches, improving the hydration rate or preventing the reverse reaction.
