WebbIn this study, we report that increase in the polyadenylation of histone mRNA contributes to increased levels of H2A1H and H3.2 in NDEA-induced HCC. The persistent exposure to carcinogen with polyadenylation of histone mRNA increases the total histone pool resulting in aneuploidy. WebbThe molecular basis of residual histone retention after the nearly genome-wide histone-to-protamine replacement during late spermatogenesis is a critical and open question. Our …

(b) CBC forms a complex with Ars2 and promotes miRNA biogenesis by mediating pri-miRNA processing. (c) CBC/Ars2 promotes pre-mRNA processing of replication-dependent histone transcripts. (d) CBC promotes … Webb6 apr. 2024 · Replication-dependent histones have a stem-loop structure at the 3′ end of messenger RNA (mRNA) and are stabilized by stem-loop binding protein (SLBP). Moreover, loss of SLBP and imbalance in the level of ARE (adenylate-uridylate-rich elements)-binding proteins, HuR, and BRF1 are associated with the polyadenylation of …

Each takes a similar strategy to capture both properties, but with... WebbThe U7 snRNP involved in histone RNA 3′ processing contains a structurally similar but biochemically unique Sm core in which two of these proteins, Sm D1 and D2, are replaced by Lsm10 and by another as yet unknown component. Here we characterize this factor, termed Lsm11, as a novel Sm-like protein with apparently two distinct functions.

Histone post-translational modifications were first identified and listed as having a potential regulatory role on the synthesis of RNA in 1964. Since then, over several decades, chromatin theory has evolved. Chromatin subunit models as well as the notion of the nucleosome were established in 1973 and 1974, respectively. ... clipart daisy black and whiteThe histone 3′ UTR stem-loop is an RNA element involved in nucleocytoplasmic transport of the histone mRNAs, and in the regulation of stability and of translation efficiency in the cytoplasm.
