Webb6 mars 2024 · The nucleosome comprises a histone octamer formed of an H3-H4 tetramer and two flanking H2A-H2B dimers that package 146 bp of DNA. While studies have established H3-H4 as a central unit for transferring long-term epigenetic memory during DNA replication via histone recycling, we know less regarding the reuse of H2A-H2B.

Rather, replication stress inhibits transcription of histone genes by removing Spt10p and Spt21p from histone promoters.

WebbHence, histone mRNAs need special treatment to prevent them from being de-stabilized and triggering innate immune reactions. Curiously, relatively little is known how this is done, and this project will address these question, using genetic and biochemical approaches.
