• Arc interacts with the integral endoplasmic reticulum protein, calnexin 

      Myrum, Craig; Soule, Jonathan; Bittins, Margarethe; Cavagnini, Kyle; Goff, Kevin; Ziemek, Silje Karina; Eriksen, Maria Steene; Patil, Sudarshan; Szum, Adrian; Nair Raveendran, Rajeevkumar; Bramham, Clive R. (Peer reviewed; Journal article, 2017-09-20)
      Activity-regulated cytoskeleton-associated protein, Arc, is a major regulator of long-term synaptic plasticity and memory formation. Here we reveal a novel interaction partner of Arc, a resident endoplasmic reticulum ...
    • Cognitive function and brain plasticity in a rat model of shift work: role of daily rhythms, sleep and glucocorticoids 

      Marti, Andrea Rørvik; Pedersen, Torhild; Wisor, Jonathan P.; Mrdalj, Jelena; Holmelid, Øystein; Patil, Sudarshan; Meerlo, Peter; Bramham, Clive R.; Grønli, Janne (Journal article; Peer reviewed, 2020)
      Many occupations require operations during the night-time when the internal circadian clock promotes sleep, in many cases resulting in impairments in cognitive performance and brain functioning. Here, we use a rat model ...
    • CREB family transcription factors are major mediators of BDNF transcriptional autoregulation in cortical neurons 

      Esvald, Eli-Eelika; Tuvikene, Jürgen; Sirp, Alex; Patil, Sudarshan; Bramham, Clive R.; Timmusk, Tõnis (Peer reviewed; Journal article, 2020)
      BDNF signaling via its transmembrane receptor TrkB has an important role in neuronal survival, differentiation, and synaptic plasticity. Remarkably, BDNF is capable of modulating its own expression levels in neurons, forming ...
    • Dynamic Arc SUMOylation and Selective Interaction with F-Actin-Binding Protein Drebrin A in LTP Consolidation In Vivo 

      Nair Raveendran, Rajeevkumar; Patil, Sudarshan; Tiron, Adrian; Kanhema, Tambudzai; Panja, Debabrata; Schiro, Lars Erik; Parobczak, Kamil; Wilczynski, Grzegorz M; Bramham, Clive R. (Peer reviewed; Journal article, 2017-05-10)
      Activity-regulatedcytoskeleton-associated protein (Arc) protein is implicated as a master regulator of long-term forms of synaptic plasticity and memory formation, but the mechanisms controlling Arc protein function are ...
    • Dynamic expression of long noncoding RNAs and repeat elements in synaptic plasticity 

      Maag, Jesper L.V.; Panja, Debabrata; Sporild, Ida; Patil, Sudarshan; Kaczorowski, Dominik C.; Bramham, Clive R.; Dinger, Marcel E.; Wibrand, Karin (Peer reviewed; Journal article, 2015-10-01)
      Long-term potentiation (LTP) of synaptic transmission is recognized as a cellular mechanism for learning and memory storage. Although de novo gene transcription is known to be required in the formation of stable LTP, the ...
    • No escaping the rat race: simulated night shift work alters the time-of-day variation in BMAL1 translational activity in the prefrontal cortex 

      Marti, Andrea Rørvik; Patil, Sudarshan; Mrdalj, Jelena; Meerlo, Peter; Skrede, Silje; Pallesen, Ståle; Pedersen, Torhild; Bramham, Clive R.; Grønli, Janne (Peer reviewed; Journal article, 2017-10-04)
      Millions of people worldwide work during the night, resulting in disturbed circadian rhythms and sleep loss. This may cause deficits in cognitive functions, impaired alertness and increased risk of errors and accidents. ...
    • The RNA-Binding Protein hnRNP K Mediates the Effect of BDNF on Dendritic mRNA Metabolism and Regulates Synaptic NMDA Receptors in Hippocampal Neurons 

      Leal, Graciano; Comprido, Diogo; de Luca, Pasqualino; Morais, Eduardo; Rodrigues, Luís; Mele, Miranda; Santos, Ana R.; Costa, Rui O.; Pinto, Maria Joana; Patil, Sudarshan; Berentsen, Birgitte; Afonso, Pedro; Carreto, Laura; Li, Ka Wan; Pinheiro, Paulo; Almeida, Ramiro D.; Santos, Manuel A. S.; Bramham, Clive R.; Duarte, Carlos B. (Peer reviewed; Journal article, 2017-11)
      Brain-derived neurotrophic factor (BDNF) is an important mediator of long-term synaptic potentiation (LTP) in the hippocampus. The local effects of BDNF depend on the activation of translation activity, which requires the ...
    • Structure of the ALS Mutation Target Annexin A11 Reveals a Stabilising N-Terminal Segment 

      Lillebostad, Peder August Gudmundsen; Raasakka, Arne; Hjellbrekke, Silje Johannessen; Patil, Sudarshan; Røstbø, Trude Kvalnes; Hollås, Hanne; Sakya, Siri; Szigetvari, Peter Daniel; Vedeler, Anni; Kursula, Petri (Journal article; Peer reviewed, 2020)
      The functions of the annexin family of proteins involve binding to Ca2+, lipid membranes, other proteins, and RNA, and the annexins share a common folded core structure at the C terminus. Annexin A11 (AnxA11) has a long ...
