Phosphorylation des histones
WebPhosphorylierte Histone wurden durch Gelfiltration und Kationenaustauschchromatographie aus Säureextrakten von Zellkernen muriner Mammatumoren isoliert. Histonphosphorylierung fand sowohl in vivo nach Verabfolgung von P- 32 an C 3 H-Mäusen als auch in vitro nach Inkubation isolierter Zellkerne mit radioaktivem Phosphat statt. WebPhosphorylation of serine residues at histone H3 is a highly dynamic process that creates together with acetylation and methylation marks at neighboring lysine residues specific combinatorial patterns that are read by specific detector proteins.
