Web7 May 2024 · SETDB1-Mediated Retroelement Silencing: Recruitment of SETDB1 to Retroelements It is supposed that heterochromatin formation needs the following steps: (1) de novo recruitment of a writer protein, (2) spreading of heterochromatin, and (3) maintenance of heterochromatin during cell division. WebThe classical view of gene regulation draws from prokaryotic models, where responses to environmental changes involve operons regulated by sequence-specific protein interactions with DNA, although it is now known that operons are also modulated by small RNAs. In eukaryotes, pathways based on microRNAs (miR) regulate the readout of genomic …
