WebbFör 1 dag sedan · Hexasomes, a type of subnucleosome, are formed when an H2A:H2B dimer is removed from a canonical nucleosome during transcription elongation or DNA replication and/or repair [ 10 ]. A hexasome wraps ~100–110 bp of DNA with an H2A:H2B dimer asymmetrically detached at the entry or exit site [ 10 ]. WebbReducing tau levels improves cognitive function in mouse models of AD and FTDP-17, but the mechanisms regulating the turnover of pathogenic tau are unknown. We found that tau is acetylated and that tau acetylation prevents degradation of phosphorylated tau (p-tau).

"WebbEvidence for octasome formation has also been reported. When Cse4 is usually mildly overproduced in budding yeast, octasome-sized particles misincorporate into chromosome arms, especially at sites of high nucleosome turnover (13), and it appears that high-level expression of Drosophila CID can also produce octasomes (23).
