The double face of the histone variant h3.3
WebHistone H3 variants contribute to chromatin dynamics through the timing and sites of their incorporation, promoted by dedicated histone chaperones. Moreover, their individual modifications and binding partners provide distinct features at defined genomic loci. We highlight here the importance of the H3.3 replacement variant for the nuclear ...

Did you know?
WebHistone H3.3 is a highly conserved histone H3 replacement variant in metazoans and has been implicated in many important biological processes, including cell differentiation and reprogramming. Germline and somatic mutations in H3.3 genomic incorporation pathway components or in H3.3 encoding genes have been associated with human congenital ... WebJan 10, 2024 · Incorporation of canonical histone and histone variants are regulated through distinct spatial and temporal mechanisms further highlighting the additional layer of complexity that they provide to the chromatin structure. 1 In the recent years several reports have suggested that histone variants might be at play in complex diseases such as ...

WebH2A is one of the core histones. H2A forms dimers with H2B via the "hand shake" motif. Two H2A-H2B dimers in turn associate with H3-H4 tetramer to form complete nucleosome core. Structure of H2A consists of histone fold domain extended by a short αC-helix and has both N- and C-terminal tails. αC-helix and C-terminal tail form "docking domain ... WebJun 30, 2024 · Serine 31 of histone H3.3 is phosphorylated during mitosis in mammalian cells and has been shown to influence chromosome segregation. We established a screening system to identify candidate kinase (s) phosphorylating H3.3S31 by using siRNA library targeting 720 human kinases, and we confirmed the results with an independent …
WebNucleosome dynamics and properties are central to all forms of genomic activities. Among the core histones, H3 variants play a pivotal role in modulating nucleosome structure and function. Here, we focus on the impact of H3 variants on various facets of development. The deposition of the replicative H3 variant following DNA replication is essential for the …
