H4K16ac activates retrotransposons and contributes to their cis regulatory function [CUT&TAG]

ABSTRACT: Mammalian genomes harbour a large number of transposable elements (TEs) and their remnants. Most TEs are incapable of retrotransposition, however, they have evolved as cis-regulatory elements (CREs), enabling them to recruit host-encoded factors. Understanding the contribution of TEs in the regulation of the mammalian genome is an active area of research. Here we show that the male-specific lethal (MSL) complex-mediated acetylation of histone H4 lysine 16 (H4K16ac) regulates the transcription of TEs. Furthermore, H4K16ac marked TEs function as a rich source of cis regulatory elements in the human genome, wherein H4K16ac acts by maintaining the permissive chromatin structure and promoting the transcription of these TEs.

H4K16ac modification profile difference between Peg3-WT and KO MEF cells

Project description:PEG3 (Paternally Expressed Gene 3) is an imprinted gene encoding a DNA-binding protein. Two components of the mammalian MSL (Male-Specific Lethal) complex, Msl1 and Msl3, are known to be the genomic targets of PEG3. In this report, we performed genome-wide ChIP-seq experiments profiling H4K16ac levels using a set of MEF cells (Mouse Embryonic Fibroblast), the WT and KO of Peg3. The results indicated that about 10% of the mouse gene catalog showed high levels of H4K16ac levels in Peg3-KO MEFs than in Peg3-WT MEFs. This further suggests that mammalian Peg3 may control its downstream genes through the MSL complex.

Complex-dependent histone acetyltransferase activity of KAT8 determines its role in transcriptional regulation and cellular homeostasis [AP-MS]

Project description:Histone acetylation is associated with open chromatin and transcriptionally active genes. Specifically, acetylation of lysine 16 on histone H4 (H4K16ac) has been shown to prevent the assembly of nucleosomal arrays in vitro. This modification is catalyzed by the MYST-family histone acetyltransferase KAT8 (also known as MOF and MYST1), which is part of two distinct chromatin-associated complexes: NSL and MSL. While extensively studied in Drosophila, the functions of H4K16ac and the two KAT8-containing complexes in mammalian cells are not well understood. Here, we demonstrate a surprising complex-dependent activity of KAT8. We found that KAT8 catalyzes H4K5 and H4K8 acetylation as part of the NSL complex, whereas it catalyzes the bulk of H4K16 acetylation as part of the MSL complex. Furthermore, we show that the core proteins of the MSL complex and H4K16ac are not required for cell proliferation and global chromatin accessibility, whereas the NSL complex is essential for cell survival, as it is enriched at the promoters of housekeeping genes and is required for their transcription initiation. In summary, we show that KAT8 switches catalytic activity and function depending on its associated proteins, and that, as part of the NSL complex, it catalyzes H4K5 and H4K8 acetylation required for the expression of genes essential for cell survival
