Popis | Apoptotic bodies are the most condensed form of chromatin. In general, chromatin structure and function are mostly dictated by histone post-translational modifications.HP1 mobility in apoptotic cells appeared to be unique because limited exchange after photobleaching was observed for other epigenetically important proteins, including GFP-JMJD2b histone demethylase (similar to 10% fluorescence recovery) or Polycomb group-related GFP-BMI1 protein (similar to 20% fluorescence recovery). These findings imply a novel fact that only certain subset of proteins in apoptotic bodies is dynamic. |
