Activation of FADD-Dependent neuronal death pathways as a predictor of pathogenicity for LRRK2 mutations
(2016)Background Despite the plethora of sequence variants in LRRK2, only a few clearly segregate with PD. Even within this group of pathogenic mutations, the phenotypic profile can differ widely. Objective We examined multiple ... -
Affinity Crystallography Reveals Binding of Pomegranate Juice Anthocyanins at the Inhibitor Site of Glycogen Phosphorylase: The Contribution of a Sugar Moiety to Potency and Its Implications to the Binding Mode
(2020)Anthocyanins (ACNs) are dietary phytochemicals with an acknowledged therapeutic significance. Pomegranate juice (PJ) is a rich source of ACNs with potential applications in nutraceutical development. Glycogen phosphorylase ... -
The challenges of interpreting phosphoproteomics data: A critical view through the bioinformatics lens
(2016)During the last decade, there has been great progress in high-throughput (HTP) phosphoproteomics and hundreds or even thousands of phosphorylation sites (p-sites) can now be detected in a single experiment. This success ... -
Denominator changes may obscure results from single-well assays: β3-adrenoceptor ligand-induced changes of cell number as example
(2017)[No abstract available] -
Downregulation of PERK activity and eIF2α serine 51 phosphorylation by mTOR complex 1 elicits pro-oxidant and pro-death effects in tuberous sclerosis-deficient cells article
(2018)Oxidative stress determines cell fate through several mechanisms, among which regulation of mRNA translation by the phosphorylation of the alpha (α) subunit of the translation initiation factor eIF2α at serine 51 (eIF2αP) ... -
Dysregulation of caveolin-1 phosphorylation and nuclear translocation is associated with senescence onset
(2021)We recently reported that the inability of osteoarthritic (OA) chondrocytes to repair oxidative stress (OS) induced DNA damage is linked to Cav-1 overexpression/improper localization. We speculated that the senescent status ... -
Enhanced Ca2+ Entry Sustains the Activation of Akt in Glucose Deprived SH-SY5Y Cells
(2022)The two crucial cellular insults that take place during cerebral ischemia are the loss of oxygen and loss of glucose, which can both activate a cascade of events leading to neuronal death. In addition, the toxic overactivation ... -
Enhancer of rudimentary homologue interacts with scaffold attachment factor B at the nuclear matrix to regulate SR protein phosphorylation
(2017)Scaffold attachment factor B1 (SAFB1) is an integral component of the nuclear matrix of vertebrate cells. It binds to DNA on scaffold/matrix attachment region elements, as well as to RNA and a multitude of different proteins, ... -
ERK1/2 phosphorylates HIF-2α and regulates its activity by controlling its CRM1-dependent nuclear shuttling
(2019)Hypoxia-inducible factor 2 (HIF-2) is a principal component of the cellular response to oxygen deprivation (hypoxia). Its inducible subunit, HIF-2α (also known as EPAS1), is controlled by oxygen-dependent as well as ... -
Estimating the total number of phosphoproteins and phosphorylation sites in eukaryotic proteomes
(2017)Background: Phosphorylation is the most frequent post-translational modification made to proteins and may regulate protein activity as either a molecular digital switch or a rheostat. Despite the cornucopia of high-throughput ... -
An evaluation of indirubin analogues as phosphorylase kinase inhibitors
(2015)Phosphorylase kinase (PhK) has been linked with a number of conditions such as glycogen storage diseases, psoriasis, type 2 diabetes and more recently, cancer (Camus et al., 2012 [6]). However, with few reported structural ... -
HIF-2α phosphorylation by CK1δ promotes erythropoietin secretion in liver cancer cells under hypoxia
(2016)Hypoxia inducible factor 2 (HIF-2) is a transcriptional activator implicated in the cellular response to hypoxia. Regulation of its inducible subunit, HIF-2α (also known as EPAS1), involves posttranslational modifications. ... -
HMMpTM: Improving transmembrane protein topology prediction using phosphorylation and glycosylation site prediction
(2014)During the last two decades a large number of Computational methods have been developed for predicting transmembrane protein topology. Current predictors rely on topogenic signals in the protein sequence, such as the ... -
Identification of MAPK phosphorylation sites and their role in the localization and activity of hypoxia-inducible factor-1α
(2006)Hypoxia-inducible factor 1 (HIF-1) controls the expression of most genes induced by hypoxic conditions. Regulation of expression and activity of its inducible subunit, HIF-1α, involves several post-translational modifications. ... -
Indoleamine 2,3-dioxygenase, by degrading L-tryptophan, enhances carnitine palmitoyltransferase i activity and fatty acid oxidation, and exerts fatty acid-dependent effects in human alloreactive CD4+ T-cells
