Webb6 sep. 2024 · Histones are synthesised in the cytoplasm and translocate to the nucleus associated with importin proteins (also known as karyopherins) ( Bernardes and Chook, 2024 ). Once in the nucleus, importins interact with RanGTP, leading to the unloading of their cargo ( Chook and Süel, 2011 ). WebbH1t-containing repeat-element LINE and LTR chromatin domains are associated with repressive marks like methylated CpGs, histone modifications H3K9me3 and H4K20me3, and heterochromatin proteins like HP1β, Trim28, PIWIL1, etc. Apart from localization of H1t at the rDNA element, we demonstrate the extranucleolar association of this linker …
