Histone phosphorylation during sea urchin development

摘要: Abstract Studies on histone phosphorylation during transitions in chromatin structure occurring vivo spermatogenesis and early embryogenesis sea urchins are reviewed evaluated the light of recent studies synthesis frog egg extracts vitro evidence that protein kinases phosphatases play direct roles regulation cellular structure. Sperm-specific variants Sp H1 H2B maintained as phosphorylated derivatives N O/P throughout specific CS H2A embryogenesis. These developmental correlations provide clues about control a basis for interpretation data obtained from in-vitro sperm remodeling biochemical effects DNA binding. The potential consequences various events observed discussed.
