Centromeres are fundamental chromosomal structures that ensure accurate chromosome segregation during cell division. Despite their conserved and essential role in maintaining genomic stability, centromeres are subject to rapid evolutionary ...

Four decades ago, the discovery of centromere protein-A (CENP-A) marked a pivotal breakthrough in chromosome biology, revealing the epigenetic foundation of centromere identity. CENP-A, a histone H3 variant, directs the formation of the mic...
CENP-A is diluted during bovine spermatogenesis and is maintained at internally positioned centromere clusters in mature bull sperm [0.03%]

During spermatogenesis, chromatin structure is remodelled by the incorporation of distinct histone variants and associated posttranslational modifications, followed by the almost complete replacement of histones by protamines in sperm. Howe...

The centromere is a region present on every human chromosome that is essential for mediating chromosome segregation and maintaining genome stability. However, despite its fundamental role in the process of cell division, the centromere is c...

Faithful chromosome segregation is facilitated by the centromeres, specialized genomic loci, which connect chromosomes to microtubules in every cell cycle by recruiting the kinetochore complex. However, a single conserved code does not gove...

The identification of CENPA, CENPB, and CENPC by Earnshaw and Rothfield 40 years ago has revealed the remarkable diversity and complexity of centromeres and confirmed most seed plants and animals have centromeres comprised of complex satell...

Circular minichromosomes could be useful tools for plant biotechnology, yet their long-term structural stability, heritability, and effects on phenotype remain poorly understood. In this study, we report a multi-generational analysis of the...

Centromeres provide the chromosomal scaffold for the assembly of the kinetochore complex, thereby linking replicated sister chromatids to the mitotic spindle, driving their segregation into nascent daughter cells. The location and maintenan...

Eukaryotic chromosome segregation requires spindle microtubules to attach to chromosomes through kinetochores. The chromosomal locus that mediates kinetochore assembly is the centromere and is epigenetically specified in most organisms by a...

While the centromeric function is conserved and epigenetically specified by CENP-A, centromeric DNA, typically composed of satellite repeats, is highly divergent and rapidly evolving. In the species of the genus Equus (horses, asses and zeb...
