Abstract: | Histone variants functionally differentiate individual nucleosomes and, hence, act as key regulators of chromatin structure and function. Large-scale proteomic projects are now valuable sources of histone-variant discovery, showing, in particular, that somatic mammalian cells express a larger panel of histone H3 variants than previously thought, including testis-specific variants and as yet uncharacterized species. These data also suggest a tight relationship between the complexity of histone-variant expression and physiopathological states of the cells. |
