Since its discovery in 1981, ubiquitin-activating enzyme 1 was thought to be the only E1-type enzyme responsible for ubiquitin activation. Recently, a relatively uncharacterized E1 enzyme, designated ubiquitin-like modifier activating enzyme 6, was also shown to activate ubiquitin. Ubiquitin-activating enzyme 1 and ubiquitin-like modifier activating enzyme 6 are both essential proteins, and eac...
Gliomas are a heterogeneous group of cancers that predominantly arise from glial cells in the brain, but may also neural stem cells, encompassing low-grade glioma and high-grade glioblastoma. Whereas better diagnosis new treatments have improved patient survival for many cancers, glioblastomas remain challenging with highly unfavorable prognosis. This review discusses super-family enzymes, 2-ox...
Histone methylation levels, which are determined by the action of both histone demethylases and methyltransferases, impact multiple biological processes by affecting gene expression activity. Methionine metabolism generates the major methyl donor S-adenosylmethionine (SAM) for histone methylation. The functions of methionine metabolic enzymes in regulating biological processes as well as the in...
Epigenetic regulation of chromatin structure is a fundamental process for eukaryotes. Regulators include DNA methylation, microRNAs and chromatin modifications. Within the chromatin modifiers, one class of enzymes that can functionally bind and modify chromatin, through the removal of methyl marks, is the histone lysine demethylases. Here, we summarize the current findings of the 13 known histo...
Epigenetics is the study of heritable changes in gene expression that are not mediated at the DNA sequence level. Molecular mechanisms that mediate epigenetic regulation include DNA methylation and chromatin/histone modifications. With the identification of key histone-modifying enzymes, the biological functions of many histone posttranslational modifications are now beginning to be elucidated....
We performed whole exome sequence (WES) to identify genetic modifiers on 184 individuals with 22q11.2 deletion syndrome (22q11DS), of whom 89 case subjects had severe congenital heart disease (CHD) and 95 control subjects had normal hearts. Three genes including JMJD1C (jumonji domain containing 1C), RREB1 (Ras responsive element binding protein 1), and SEC24C (SEC24 family member C) had rare (...
Histone modification enzymes regulate gene expression by altering the accessibility of promoters to transcription factors. We sought to determine whether the genes encoding histone modification enzymes are dysregulated in pediatric acute lymphoblastic leukemia (ALL). A real-time PCR array was designed, tested and used to profile the expression of 85 genes encoding histone modification enzymes i...
