WebB. histone code. The histone code refers to the combination of epigenetic changes, such as histone modifications, that influence gene expression. These modifications include methylation, acetylation, phosphorylation, and ubiquitination, which can have various effects on chromatin structure and gene activity. WebCovalent modifications to histone tails, including methylation, acetylation, ubiquitination, sumoylation, citrullination, and phosphorylation, are well-correlated with chromatin structure (euchromatin versus heterochromatin) and accessibility, which in turn impacts transcriptional activation/silencing. For instance, histone acetylation (e.g ...
WebPhosphorylation at a highly conserved serine residue (Ser-10) in the histone H3 tail is considered to be a crucial event for the onset of mitosis. This modification appears early in the G (2) phase within pericentromeric heterochromatin and spreads in an ordered fashion coincident with mitotic chromosome condensation. WebIn recent years, the covalent modification of histone tails has emerged as a crucial step in controlling the transcription of eukaryotic genes. Phosphorylation of the serine 10 residue of the N-terminal tail of histone H3 is crucial for chromosome condensation and cell-cycle progression during mitosis and meiosis. In addition,
