H3K27 methylation and H3S28 phosphorylation‐dependent transcriptional regulation by INHAT subunit SET/TAF‐Iβ

Abstract: Edited by Ned ManteiKeywords: SET/TAF-Ib INHAT H3S28 Phosphorylation H3K27me Peptide array a b s t r a c t Significant progress has been made in understanding the relationship between histone modifications and 'reader' molecules and their effects on transcriptional regulation. A previously identified INHAT complex subunit, SET/TAF-Ib, binds to histones and inhibits histone acetylation. To investigate the binding specificities of SET/TAF-Ib to various histone modifications, we employed modified histone tail pep… Show more

“…Moreover, we performed RNA sequencing (RNA-seq) analysis to compare the effect of ZRANB1 and EZH2 on global gene expression. A total of 63 genes, including known EZH2 targets or downstream genes SERPINB2 (Kim et al, 2012), PTGS2 (encoding cyclooxygenase-2) (Coward et al, 2014), ABCA1 (Lv et al, 2016), and MMP9 (Delgado-Olguín et al, 2014), were differentially expressed (49 upregulated and 14 downregulated) by at least 1.6-fold (p < 0.05) upon knockdown of either ZRANB1 or EZH2 in LM2 cells (Figures 1G and 1H; Table S1). Taken together, our data suggest that ZRANB1 is a functional regulator of EZH2.…”

“…H3S28ph) proximal to the site of the initial modification (H3K27me3) add another layer complexity. In this example the recognition of H3K27me3 by the INHAT “reader” protein is prevented by phosphorylation of Serine 28 (H3S28ph) (Kim et al, 2012). Thisillustrates how modification of nearby residues can interfere with the recognition of specific histone marks by “reader” proteins.…”

“…A SET/INHAT inibe a acetilação de histonas por se ligar e mascarar as lisinas das histonas alvos de acetiltransferases. Além de manter histonas na forma hipoacetilada, a SET/INHAT inibe a desmetilação de sítios hipermetilados do DNA (Cervoni et al, 2002) e, assim, está envolvida na repressão transcricional de regiões específicas do DNA (Kim, Kim, et al, 2012). A relação da SET com a regulação epigenética representa um novo mecanismo que pode explicar a hipermetilação de regiões específicas em células tumorais (Cervoni et al, 2002).…”
