Birth and death of histone mrnas
WebHistone mRNAs are not rapidly degraded when DNA synthesis is inhibited or at the end of S phase in cells expressing this mutant SLBP. Replication-dependent histone mRNAs have very short 3' untranslated regions, with the stem-loop located 30 to 70 nucleotides downstream of the translation termination codon. We show here that the stability of ... WebAug 31, 2024 · Europe PMC is an archive of life sciences journal literature.
