DNA histone interaction refers to the process where histone modifications, such as acetylation and methylation, influence the structure of chromatin by altering the accessibility of transcriptional regulators to DNA-binding elements. AI generated definition based on:Trends in Pharmacological Sciences,2015 ...
Till date, there has not been much progress in studying various epigenomic marks in common bean, and therefore, the long-term objective of this research is to identify protein-DNA interaction sites in the common bean genome to include histones, as well as, non-histone proteins such as ...
Histone H5 has been labelled with fluorescein isothiocyanate (FITC) with particular attention to the reaction conditions (pH, reaction time and input FITC/H5 molar ratio) and to the complete elimination of non-covalently bound dye. We preferred to use reaction conditions which yielded non-specific ...
The circular dichroism of DNA near 275 nm is depressed by the interaction with (H2A, H2B) at low concentrations of salt. The depression increases with increasing amounts of (H2A, H2B), and reaches a plateau at an (H2A, H2B) to DNA ratio of 1.5 ( w w), at which one (H2A, H2B) ...
Given the chemical similarities between lactylation and acetylation10,31, it is likely that the former also weakens the interaction between histones and DNA32,33, and increases the efficiency with which RNAPII moves through chromatin in vitro34. Indeed, histone acylations (e.g., acetylation, ...

In addition,histoneexchange reveals new changing mechanism of DNA -histoneinteraction. 并且, 组蛋白替换揭示了DNA - 组蛋白相互作用变化的一种新的机制. 互联网 Histonemodifications are implicated in influencing gene expression. 组蛋白修饰与影响基因表达有关. ...
Monoubiquitinated by RAG1 in lymphoid cells, monoubiquitination is required for V(D)J recombination (By similarity). Ubiquitinated by the CUL4-DDB-RBX1 complex in response to ultraviolet irradiation. This may weaken the interaction between histones and DNA and facilitate DNA accessibility to repair ...
Histones H1 and H5 interact preferentially with crossovers of double-helical DNA. The interaction of the linker histones H1 and H5 from chicken erythrocyte chromatin with pBR322 was studied as a function of the number of superhelical tur... Krylov,Leuba,V Holde,... - 《Proceedings of the Nat...
DNMT1 is recruited by PCNA and UHRF1 to maintain DNA methylation after replication. UHRF1 recognizes hemimethylated DNA substrates via the SRA domain, but also repressive H3K9me3 histone marks with its TTD. With systematic mutagenesis and functional assa
