WebbA major step in regulation of mammalian histone mRNA is a rapid alteration in the half-life of histone mRNA in response to changes in the rate of DNA synthesis, allowing the cell … Webb1 nov. 2024 · We show here that histone mRNAs are degraded by both 5′ to 3′ and 3′ to 5′ pathways; however, DDC/DRC activation does not trigger decay of histone mRNA. 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.
