Biochemical and cellular analysis of Ogden syndrome reveals downstream Nt-acetylation defects
Myklebust, Line Merethe; Van Damme, Petra; Støve, Svein Isungset; Dörfel, Max J; Abboud, Angèle; Kalvik, Thomas Vikestad; Grauffel, Cédric; Jonckheere, Veronique; Wu, Yiyang; Swensen, Jeffrey; Kaasa, Hanna; Liszczak, Glen; Marmorstein, Ronen; Reuter, Nathalie; Lyon, Gholson J; Gevaert, Kris; Arnesen, Thomas (Peer reviewed; Journal article, 2014-12-03)The X-linked lethal Ogden syndrome was the first reported human genetic disorder associated with a mutation in an N-terminal acetyltransferase (NAT) gene. The affected males harbor an Ser37Pro (S37P) mutation in the gene ... -
Characterization of Evolutionarily Conserved Trypanosoma cruzi NatC and NatA-N-Terminal Acetyltransferase Complexes
Ochaya, Stephen; Franzén, Oscar; Buhwa, Doreen Asiimwe; Foyn, Håvard; Butler, Claire E.; Støve, Svein Isungset; Tyler, Kevin M.; Arnesen, Thomas; Matovu, Enock; Åslund, Lena; Andersson, Bjørn (Peer reviewed; Journal article, 2019-03-06)Protein N-terminal acetylation is a co- and posttranslational modification, conserved among eukaryotes. It determines the functional fate of many proteins including their stability, complex formation, and subcellular ... -
Inhibition of VMAT2 by β2-adrenergic agonists, antagonists, and the atypical antipsychotic ziprasidone
Støve, Svein Isungset; Skjevik, Åge Aleksander; Teigen, Knut; Martinez, Aurora (Journal article; Peer reviewed, 2022)Vesicular monoamine transporter 2 (VMAT2) is responsible for packing monoamine neurotransmitters into synaptic vesicles for storage and subsequent neurotransmission. VMAT2 inhibitors are approved for symptomatic treatment ... -
NAA10 dysfunction with normal NatA-complex activity in a girl with non-syndromic ID and a de novo NAA10 p.(V111G) variant - a case report
Mc Tiernan, Nina; Støve, Svein Isungset; Aukrust, Ingvild; Mårli, Marita Torrissen; Myklebust, Line Merethe; Houge, Gunnar; Arnesen, Thomas (Peer reviewed; Journal article, 2018)Background: The NAA10-NAA15 (NatA) protein complex is an N-terminal acetyltransferase responsible for acetylating ~ 40% of eukaryotic proteins. In recent years, NAA10 variants have been found in patients with an X-linked ... -
NAA10 mutation causing a novel intellectual disability syndrome with Long QT due to N-terminal acetyltransferase impairment
Casey, Jillian P.; Støve, Svein Isungset; McGorrian, Catherine; Galvin, Joseph; Blenski, Marina; Dunne, Aimee; Ennis, Sean; Brett, Francesca; King, Mary D.; Arnesen, Thomas; Lynch, Sally Ann (Peer reviewed; Journal article, 2015-11-02)We report two brothers from a non-consanguineous Irish family presenting with a novel syndrome characterised by intellectual disability, facial dysmorphism, scoliosis and long QT. Their mother has a milder phenotype including ... -
De novo missense mutations in the NAA10 gene cause severe non-syndromic developmental delay in males and females
Popp, Bernt; Støve, Svein Isungset; Endele, Sabine; Myklebust, Line Merethe; Hoyer, Juliane; Sticht, Heinrich; Azzarello-Burri, Silvia; Rauch, Anita; Arnesen, Thomas; Reis, André (Peer reviewed; Journal article, 2015)Recent studies revealed the power of whole-exome sequencing to identify mutations in sporadic cases with non-syndromic intellectual disability. We now identified de novo missense variants in NAA10 in two unrelated individuals, ... -
Optimized bisubstrate inhibitors for the actin N-terminal acetyltransferase NAA80
Myklebust, Line Merethe; Baumann, Markus; Støve, Svein Isungset; Foyn, Håvard; Arnesen, Thomas; Haug, Bengt Erik (Journal article; Peer reviewed, 2023)Acetylation of protein N-termini is one of the most common protein modifications in the eukaryotic cell and is catalyzed by the N-terminal acetyltransferase family of enzymes. The N-terminal acetyltransferase NAA80 is ... -
An organellar Nα-acetyltransferase, Naa60, acetylates cytosolic n termini of transmembrane proteins and maintains golgi integrity
Aksnes, Henriette; Van Damme, Petra; Goris, Marianne; Starheim, Kristian K.; Marie, Michael Bruno Eric; Støve, Svein Isungset; Hoel, Camilla; Kalvik, Thomas Vikestad; Hole, Kristine; Glomnes, Nina; Furnes, Clemens; Ljostveit, Sonja; Ziegler, Mathias; Niere, Marc; Gevaert, Kris; Arnesen, Thomas (Peer reviewed; Journal article, 2015-02-26)N-terminal acetylation is a major and vital protein modification catalyzed by N-terminal acetyltransferases (NATs). NatF, or Nα-acetyltransferase 60 (Naa60), was recently identified as a NAT in multicellular eukaryotes. ... -
A scavenger receptor B (CD36)-like protein is a potential mediator of intestinal heme absorption in the hematophagous ectoparasite Lepeophtheirus salmonis
Eichner, Christiane; Støve, Svein Isungset; Martinez, Aurora; Nilsen, Frank; Dondrup, Michael (Peer reviewed; Journal article, 2019-03-12)Intestinal absorption of heme has remained enigmatic for years, even though heme provides the most bioavailable form of iron. The salmon louse, Lepeophtheirus salmonis, is a heme auxotrophic ectoparasite feeding on large ...
