Webb1 feb. 2008 · Radiolabeled biotin was readily detectable on carboxylases but not on histones, implying very low levels of biotin in the nucleus attached to histone proteins (< 0.03% biotinylation). In conclusion, we would caution against the use of streptavidin for investigating histone biotinylation. Webb8 feb. 2024 · The addition of biotin to histones plays a significant role in cellular proliferation, gene silencing, and DNA repair and stability [63, 17, 1]. Low levels of biotin can lead to inadequate histone biotinylation, which may result in genomic instability and abnormal gene expression (cellular production) and thus increases the risks of cancer.

Webb3 aug. 2005 · Histones are small proteins (11–22 kDa) that mediate the folding of DNA into chromatin. The following five major classes of histones have been identified in eukaryotic cells: H1, H2A, H2B, H3 and H4 [].DNA is wrapped around octamers of core histones, each consisting of one H3–H3–H4–H4 tetramer and two H2A–H2B dimers, to form the … Webb7 okt. 2009 · The covalent binding of the vitamin biotin to histones is mediated by holocarboxylase synthetase (HCS) ( 20, 21 ).
