Transcriptional repression of ANGPT1 by histone H3K9 demethylase KDM3B
Here we report that the H3K9 demethylase KDM3B represses transcription of the angiogenesis regulatory gene, ANGPT1. Negative regulation of ANGPT1 by KDM3B is independent of its Jumonji (JmjC) domain-mediated H3K9 demethylase activity. We demonstrate that KDM3B downregulates ANGPT1 via interaction with SMRT, and suggest that the repressor complex is formed at the promoter area of ANGPT1. Using M...
متن کاملThe Histone H3K9 Demethylase Kdm3b Is Required for Somatic Growth and Female Reproductive Function
Kdm3b is a Jumonji C domain-containing protein that demethylates mono- and di-methylated lysine 9 of histone H3 (H3K9me1 and H3K9me2). Although the enzyme activity of Kdm3b is well characterized in vitro, its genetic and physiological function remains unknown. Herein, we generated Kdm3b knockout (Kdm3bKO) mice and observed restricted postnatal growth and female infertility in these mice. We fou...
متن کاملJMJD6 is a histone arginine demethylase.
Arginine methylation occurs on a number of proteins involved in a variety of cellular functions. Histone tails are known to be mono- and dimethylated on multiple arginine residues where they influence chromatin remodeling and gene expression. To date, no enzyme has been shown to reverse these regulatory modifications. We demonstrate that the Jumonji domain-containing 6 protein (JMJD6) is a JmjC...
متن کاملHistone H3K9 Demethylase JMJD2B Activates Adipogenesis by Regulating H3K9 Methylation on PPARγ and C/EBPα during Adipogenesis
Previous studies have shown that tri- or di-methylation of histone H3 at lysine 9 (H3K9me3/me2) on the promoter of the peroxisome proliferator-activated receptor γ (PPARγ) and CCAAT/enhancer-binding protein α (C/EBPα) contribute to the repression of PPARγ and C/EBPα and inhibition of adipogenesis in 3T3-L1 preadipocytes. The balance of histone methylation is regulated by histone methyltransfera...
متن کاملDemethylase activity is directed by histone acetylation.
Mammalian genomes are compartmentalized into dense inactive chromatin that is hypermethylated and active open chromatin that is hypomethylated. It is generally accepted that this bimodal pattern of methylation is established during development and is then faithfully inherited through subsequent cell divisions by a maintenance DNA methyltransferase (DNMT1). The pattern of methylation is believed...
