Webb6 aug. 2024 · Three components, the nucleolus, Cajal body and histone locus body, can mix in early zebrafish embryogenesis when transcription is silenced . The functions of the Cajal body and the histone locus body in the nucleus are to organize the assembly of snoRNPs and the production of histone messenger RNA (mRNA), respectively (58, 59). Webb25 aug. 2024 · Unlike most pre-mRNAs, histone pre-mRNAs are not polyadenylated; instead their 3’ends are bound and cleaved by the U7 snRNP complex to produce mature histone mRNAs 31,88. This process is thought to occur within nuclear structures called Histone Locus Bodies (HLBs) 32,80.
