Biochimica Et Biophysica Acta
|December 14, 2011
Summary
Centromeres, essential for inheritance, are epigenetically marked by CENP-A and other proteins. Recent research clarifies how these proteins assemble functional centromeric chromatin for cell division.
Area of Science:
- Molecular Biology
- Cell Biology
- Genetics
Background:
- Centromeres are crucial for accurate chromosome segregation during cell division.
- Their epigenetic specification, rather than DNA sequence, is key to their function.
- The histone H3 variant CENP-A is a primary epigenetic marker for centromeres.
Purpose of the Study:
- To review recent advances in identifying and characterizing centromere proteins.
- To highlight new findings on the assembly of functional centromeric chromatin.
Main Methods:
- Literature review of recent research on centromere proteins.
- Focus on studies detailing centromeric chromatin assembly mechanisms.
Main Results:
- Identification of novel proteins involved in centromere formation and maintenance.
- Elucidation of the roles of these proteins in assembling centromeric chromatin.
- Understanding the epigenetic mechanisms underlying centromere specification.
Conclusions:
- Centromere assembly is a complex process involving CENP-A and multiple accessory proteins.
- Epigenetic regulation is central to establishing and maintaining centromere identity.
- Continued research is vital for a comprehensive understanding of chromosomal inheritance.

02:30Histone Variants at the Centromere
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3 variants are also...
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.

02:05Duplication of Chromatin Structure
The process of chromosome duplication during cell division requires genome-wide disruption and re-assembly of chromatin. The chromatin structure must be accurately inherited, reassembled, and maintained in the daughter cells to ensure lineage propagation.
The basic unit of the chromatin is the nucleosome, consisting of DNA wrapped around octameric histone proteins and short stretches of linker DNA separating individual nucleosomes. The histone proteins within the nucleosome have their...

03:17Inheritance of Chromatin Structures
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying DNA...
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.

02:38Heterochromatin
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions that take up more dye are called heterochromatin. Heterochromatin is further classified into two forms – constitutive heterochromatin and facultative heterochromatin.
Constitutive heterochromatin: It is a highly compact region of chromatin that is mostly concentrated in the centromere and telomere. Unlike euchromatin, the amino acid at 9th...
