2013年5月15日 · KDM4/JMJD2 proteins are demethylases that target histone H3 on lysines 9 and 36 and histone H1.4 on lysine 26. This protein family consists of three ~130-kDa proteins (KDM4A-C) and KDM4D/JMJD2D, which is half the size, lacks the double PHD and Tudor domains that are epigenome readers and present in the …

2022年9月1日 · JMJD2 is one of the largest JMJD subfamilies and is comprised of JMJD2A-D proteins, also referred to as KDM4A-D. JMJD2 family members take active parts in multiple physiological processes ...

2021年1月13日 · Histone demethylase JMJD2 (also known as KDM4) family proteins have been previously shown to support self-renewal and differentiation of stem cells. However, their roles in the context of the...

Here we report studies on the inhibition of the JMJD2 subfamily of histone demethylases, employing binding analyses by nondenaturing mass spectrometry (MS), dynamic combinatorial chemistry coupled to MS, turnover assays, and crystallography.

2016年10月6日 · Recent research shows dysregulation in epigenetic regulatory mechanisms, particularly the transcriptionally repressive di- and tri-methylation of histone 3 lysine 9 (H3K9me2/me3) in nucleus...

2011年5月9日 · JMJD2 proteins are lysine trimethyl–specific histone demethylases that catalyze the demethylation of trimethylated H3K9 (H3K9me3) and H3K36 (H3K36me3). Genome-wide studies show that H3K9me3 is enriched in heterochromatin (15), which predicts that the H3K9me3 demethylase activities of JMJD2 proteins may act as transcriptional activators.

KDM4/JMJD2 proteins are demethylases that target histone H3 on lysines 9 and 36 and histone H1.4 on lysine 26. This protein family consists of three ~130 kDa proteins (KDM4A–C) and KDM4D/JMJD2D, which is half the size, lacks the double PHD and Tudor domains that are epigenome readers and present in the other KDM4 proteins, and has a different ...

2013年1月8日 · JMJD2 lysine demethylases (KDMs) participate in diverse genomic processes. Most JMJD2 homologs display dual selectivity toward H3K9me3 and H3K36me3, with the exception of JMJD2D, which is specific for H3K9me3. Here, we report the crystal structures of the JMJD2D⋅2-oxoglutarate⋅H3K9me3 ternary comple …

KDM4/JMJD2是H3K9-和H3K36-特异性去甲基化酶，被认为有望成为携带MLL易位的急性髓系白血病(AML)的治疗靶点。Karl Agger等人研究耗竭KDM4活性对正常造血的长期影响，以探讨持续抑制这些酶的潜在副作用。

2023年7月15日 · Methods: To evaluate the effects of Jumonji C domain-containing (JMJD2) protein subfamily JMJD2A-2D proteins on HBV replication, we used lentivirus-based RNA interference to suppress the expression of isoforms JMJD2A-2D in HBV-infected cells. JMJD2D-knockout mice were generated to obtain an HBV-injected model for in vivo experiments. Co ...
