Achilles, a new family of transcriptionally active retrotransposons from the olive fruit fly, with y chromosome preferential distribution
(2015)Sex chromosomes have many unusual features relative to autosomes. The in depth exploration of their structure will improve our understanding of their origin and divergence (degeneration) as well as the evolution of genetic ... -
Aldehyde dehydrogenase 1B1: Molecular cloning and characterization of a novel mitochondrial acetaldehyde-metabolizing enzyme
(2010)Ethanol-induced damage is largely attributed to its toxic metabolite, acetaldehyde. Clearance of acetaldehyde is achieved by its oxidation, primarily catalyzed by the mitochondrial class II aldehyde dehydrogenase (ALDH2). ... -
Amino acid signatures in the HLA class II peptide-binding region associated with protection/susceptibility to the severe West Nile Virus disease
(2018)The MHC class II region in humans is highly polymorphic. Each MHC molecule is formed by an α and a β chain, produced by different genes, creating an antigen-binding groove. In the groove there are several pockets into which ... -
Anosmic flies: what Orco silencing does to olive fruit flies
(2020)Background: The olive fruit fly (Bactrocera oleae) is the most destructive pest of the olive cultivation worldwide causing significant production losses and olive fruit impoverishment, as its larvae feed exclusively on the ... -
AtHESPERIN: A novel regulator of circadian rhythms with poly(A)-degrading activity in plants
(2016)We report the identification and characterization of a novel gene, AtHesperin (AtHESP) that codes for a deadenylase in Arabidopsis thaliana. The gene is under circadian clock-gene regulation and has similarity to the ... -
The complex evolutionary history of aminoacyl-tRNA synthetases
(2017)Aminoacyl-tRNA synthetases (AARSs) are a superfamily of enzymes responsible for the faithful translation of the genetic code and have lately become a prominent target for synthetic biologists. Our largescale analysis of > ... -
Dimerization of the AtoC response regulator and modelling of its binding to DNA
(2010)Bacterial signal transduction systems can be viewed as an entity of multi-sensory and output domains, whereas the functions of response regulators play a pivotal role in the complex network interactions. One crucial property ... -
Evidence for disulfide bonds in SR Protein Kinase 1 (SRPK1) that are required for activity and nuclear localization
(2017)Serine/arginine protein kinases (SRPKs) phosphorylate Arg/Ser dipeptide-containing proteins that play crucial roles in a broad spectrum of basic cellular processes. The existence of a large internal spacer sequence that ... -
Expression of human serum albumin (HSA) mRNA in human granulosa cells: Potential correlation of the 95 amino acid long carboxyl terminal of HSA to gonadotrophin surge-attenuating factor
(2006)Introduction: According to previous studies, gonadotrophin surge-attenuating factor (GnSAF), which is assumed to be produced in human granulosa cells, has a homology with the carboxyl terminal of the human serum albumin ... -
A freestanding proofreading domain is required for protein synthesis quality control in Archaea
(2004)Threonyl-tRNA synthetase (ThrRS) participates in protein synthesis quality control by selectively editing the misacylated species Ser-tRNAThr. In bacteria and eukaryotes the editing function of ThrRS resides in a highly ... -
Frequency dependent non-thermal effects of oscillating electric fields in the microwave region on the properties of a solvated lysozyme system: A molecular dynamics study
(2017)The use of microwaves in every day's applications raises issues regarding the non thermal biological effects of microwaves. In this work we employ molecular dynamics simulations to advance further the dielectric studies ... -
HIF-1α-derived cell-penetrating peptides inhibit ERK-dependent activation of HIF-1 and trigger apoptosis of cancer cells under hypoxia
(2019)Hypoxia is frequently encountered in the microenvironment of solid tumors. Hypoxia-inducible factors (HIFs), the main effectors of cell response to hypoxia, promote cancer cell survival and progression. HIF-1α, the ... -
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. ... -
HLA class II peptide-binding-region analysis reveals funneling of polymorphism in action
(2021)Background: HLA-class II proteins hold important roles in key physiological processes. The purpose of this study was to compile all class II alleles reported in human population and investigate patterns in pocket variants ... -
Hypoxia-induced Changes in SUMO Conjugation Affect Transcriptional Regulation under Low Oxygen
(2019)Hypoxia occurs in pathological conditions, such as cancer, as a result of the imbalance between oxygen supply and consumption by proliferating cells. HIFs are critical molecular mediators of the physiological response to ... -
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. ... -
In silico investigation of the viroporin E as a vaccine target against SARS-CoV-2
