Does needle puncture in rabbit functional spinal units alter rotational biomechanics?
These findings suggest that disk puncture and stab can destabilize FSUs in primary rotations.
RanBP7 can decondense sperm nuclei and decrease H1 binding, but the rapid dynamics of H1 on chromatin depend on other cytoplasmic factors. Cytoplasm greatly impairs the activity of individual H1 domains, and only the full-length protein can condense chromatin properly. Our findings begin to bridge the gap between purified and in vivo chromatin systems.
