Summary
Histone post-translational modifications (PTMs) regulate chromatin function. Recent advances clarify how these PTMs, and the proteins that modify them, orchestrate complex cellular activities.
Area of Science:
- Epigenetics and Molecular Biology
- Chromatin Biology
- Genomics
Background:
- Histones are core components of eukaryotic DNA packaging.
- Histone post-translational modifications (PTMs) are critical regulators of chromatin structure and function.
- The histone code hypothesis proposes that PTMs dictate chromatin-based processes.
Observation:
- Over the past decade, understanding of histone PTMs and associated enzymes has significantly advanced.
- Numerous effector proteins that recognize and bind histone PTMs have been identified.
- The combinatorial nature of histone PTMs in regulating biological activities is increasingly evident.
Findings:
- The field has progressed from limited knowledge to a comprehensive view of histone PTMs.
- Enzymes responsible for establishing and removing histone PTMs are better characterized.
- Combinations of histone PTMs play a crucial role in regulating chromatin activities.
Implications:
- Histone PTMs function in complex combinations to regulate diverse chromatin-associated activities.
- Continued technological advancements will further elucidate the mechanisms of histone PTMs.
- This review provides a current perspective on the histone code hypothesis and future research directions.

02:41Chromatin Structure Regulates pre-mRNA Processing
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

02:35Chromatin Position Affects Gene Expression
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

01:01Euchromatin
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions take up more dye, appearing darker, while the less-compact areas take up less dye and appear lighter. Based on the compaction level, chromatins are classified into two primary forms – euchromatin and heterochromatin.
Euchromatin is the less dense region of the chromatin and stains lighter. Euchromatin contains histone H3 extensively...

02:25Spreading of Chromatin Modifications
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

02:21Chromatin Packaging
Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter?
The chromatin
In combination with specialized DNA binding protein called Histones, the DNA double helix forms a compact DNA: protein complex called chromatin. The chromatin itself is further compacted into higher-order structures.
