Arc is a flexible modular protein capable of reversible self-oligomerization
Myrum, Craig; Baumann, Anne; Bustad, Helene J.; Flydal, Marte Innselset; Mariaule, Vincent; Alvira, Sara; Cuéllar, Jorge; Haavik, Jan; Soulé, Jonathan; Valpuesta, José María; Márquez, José Antonio; Martinez, Aurora; Bramham, Clive R. (Peer reviewed; Journal article, 2015)The immediate early gene product Arc (activity-regulated cytoskeleton-associated protein) is posited as a master regulator of long-term synaptic plasticity and memory. However, the physicochemical and structural properties ... -
The Host-Pathogen interaction of Human Cyclophilin A and HIV-1 Vpr requires specific N-terminal and novel C-terminal domains
Solbak, Sara Marie Øie; Wray, Victor; Horvli, Ole; Raae, Arnt Johan; Flydal, Marte Innselset; Henklein, Petra; Henklein, Peter; Nimtz, Manfred; Schubert, Ulrich; Fossen, Torgils (Peer reviewed; Journal article, 2011-12-20)Background: Cyclophilin A (CypA) represents a potential key molecule in future antiretroviral therapy since inhibition of CypA suppresses human immunodeficiency virus type 1 (HIV-1) replication. CypA interacts with the ... -
Inhibition of the Human Hsc70 System by Small Ligands as a Potential Anticancer Approach
Dublang, Leire; Underhaug, Jarl; Flydal, Marte Innselset; Velasco-Carneros, Lorea; Maréchal, Jean-Didier; Moro, Fernando; Boyano, Maria Dolores; Martinez, Aurora; Muga, Arturo (Journal article; Peer reviewed, 2021)Heat shock protein (Hsp) synthesis is upregulated in a wide range of cancers to provide the appropriate environment for tumor progression. The Hsp110 and Hsp70 families have been associated to cancer cell survival and ... -
Phenylalanine Hydroxylase from Legionella pneumophila Is a Thermostable Enzyme with a Major Functional Role in Pyomelanin Synthesis
Flydal, Marte Innselset; Chatfield, Christa H.; Zheng, Huaixin; Gunderson, Felizza F.; Aubi, Oscar; Cianciotto, Nicholas P.; Martinez, Aurora (Peer reviewed; Journal article, 2012-09-26)Background: Legionella pneumophila is a pathogenic bacterium that can cause Legionnaires’ disease and other non-pneumonic infections in humans. This bacterium produces a pyomelanin pigment, a potential virulence factor ... -
Regulation of tyrosine hydroxylase is preserved across different homo- and heterodimeric 14-3-3 proteins
Ghorbani, Sadaf; Fossbakk, Agnete; Jorge Finnigan, Ana; Flydal, Marte Innselset; Haavik, Jan; Kleppe, Rune (Peer reviewed; Journal article, 2016-05)Tyrosine hydroxylase (TH) is regulated by members of the 14-3-3 protein family. However, knowledge about the variation between 14-3-3 proteins in their regulation of TH is still limited. We examined the binding, effects ... -
Stable preparations of tyrosine hydroxylase provide the solution structure of the full-length enzyme
Bezem, Maria Teresa; Baumann, Anne; Skjærven, Lars; Meyer, Romain; Kursula, Petri; Martinez, Aurora; Flydal, Marte Innselset (Peer reviewed; Journal article, 2016-07-27)Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the biosynthesis of catecholamine neurotransmitters. TH is a highly complex enzyme at mechanistic, structural, and regulatory levels, and the preparation of ... -
Structural and thermodynamic insight into phenylalanine hydroxylase from the human pathogen Legionella pneumophila
Leiros, Hanna-Kirsti S.; Flydal, Marte Innselset; Martinez, Aurora (Peer reviewed; Journal article, 2013-08-19)Phenylalanine hydroxylase from Legionella pneumophila (lpPAH) has a major functional role in the synthesis of the pigment pyomelanin, which is a potential virulence factor. We present here the crystal structure of lpPAH, ... -
Structural mechanism for tyrosine hydroxylase inhibition by dopamine and reactivation by Ser40 phosphorylation
Bueno-Carrasco, María Teresa; Cuellar, Jorge; Flydal, Marte Innselset; Santiago, Cesar; Kråkenes, Trond-André; Kleppe, Rune; Jose R, Lopez-Blanco; Marcilla, Miguel; Teigen, Knut; Alvira, Sara; Chacón, Pablo; Martinez, Aurora; Valpuesta, José M (Journal article; Peer reviewed, 2022)Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the biosynthesis of dopamine (DA) and other catecholamines, and its dysfunction leads to DA deficiency and parkinsonisms. Inhibition by catecholamines and ...
