Ternary structure reveals mechanism of a membrane diacylglycerol kinase [PDF]

, 2015
Diacylglycerol kinase catalyses the ATP-dependent conversion of diacylglycerol to phosphatidic acid in the plasma membrane of Escherichia coli. The small size of this integral membrane trimer, which has 121 residues per subunit, means that available ...

Epigenetic regulation of diacylglycerol kinase alpha promotes radiation-induced fibrosis

Nature Communications, 2016
Radiotherapy can induce fibrosis in cancer patients, limiting its use in clinical settings. Here, the authors identify a differentially methylated enhancer of the lipid kinase DGKA in fibroblasts from breast cancer patients developing fibrosis after ...

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Activation of protein kinase C by cis- and trans-fatty acids and its potentiation by diacylglycerol [PDF]

, 1988
Both cis- and trans-unsaturated but not saturated fatty acids activated protein kinase C purified to apparent homogeneity from rat brain. Fatty-acid-induced enzyme activation was not more than additive with that by phospholipids and was potentiated by ...

The role of diacylglycerol in the exocytosis of the sperm acrosome. Studies using diacylglycerol lipase and diacylglycerol kinase inhibitors and exogenous diacylglycerols [PDF]

Biochemical Journal, 1992
When ram spermatozoa were treated with Ca2+ and the ionophore A23187 to induce acrosomal exocytosis, a rise in diacylglycerol (DAG) mass was observed, concomitant with a rapid breakdown of [32P]P1-labelled phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 4-phosphate and a rise in [32P]Pi-labelled phosphatidate. Inclusion of the DAG lipase

Incorporation of 13-hydroxyoctadecadienoic acid (13-HODE) into epidermal ceramides and phospholipids: phospholipase C-catalyzed release of novel 13-HODE-containing diacylglycerol.

Journal of Lipid Research, 1994
Ceramides and phospholipids constitute two important structural lipids of normal skin that are notably rich in polyunsaturated fatty acids. Although linoleic acid (LA) is high in the ceramides, the localization of its 15-lipoxygenase product, 13 ...

Current status and future perspectives of platelet function‐guided precision antiplatelet therapy for patients with cerebral infarction

Neuroprotection, EarlyView.
Antiplatelet agents target the cyclooxygenase‐1 (COX‐1)/thromboxane A2 (TXA2) and adenosine diphosphate (ADP)‐P2Y12 (cytochrome P450 2C19 [CYP2C19]‐metabolized) platelet activation pathways, resulting in either drug resistance or over‐inhibition. The individualized therapeutic window balances ischemic risk (triggered by high on‐treatment platelet ...

Diacylglycerol kinase ζ controls diacylglycerol metabolism at the immunological synapse

Molecular Biology of the Cell, 2011
Diacylglycerol (DAG) generation at the T cell immunological synapse (IS) determines the correct activation of antigen-specific immune responses. DAG kinases (DGKs) α and ζ act as negative regulators of DAG-mediated signals by catalyzing DAG conversion to phosphatidic acid (PA). Nonetheless, the specific input of each enzyme and their spatial regulation

Epigenetic Regulation of Liver Fibrosis: Mechanisms and Therapeutic Implications

Portal Hypertension &Cirrhosis, EarlyView.
This review synthesizes the epigenetic mechanisms—DNA methylation, histone modifications, and non‐coding RNAs—that drive hepatic stellate cell activation and the progression of liver fibrosis. It further evaluates emerging therapeutic strategies targeting these epigenetic regulators, including DNA methyltransferase and histone deacetylase inhibitors ...

Diacylglycerol kinase β promotes dendritic outgrowth and spine maturation in developing hippocampal neurons

BMC Neuroscience, 2009
Background Diacylglycerol kinase (DGK) is an enzyme that phosphorylates diacylglycerol to phosphatidic acid and comprises multiple isozymes of distinct properties.
