      N-terminal acetylation (NTA) catalysed by N-terminal acetyltransferases (Nats) is among the most common protein modifications in eukaryotes, but its significance is still enigmatic. Here we characterize the plant NatA ...
    • Excessive Daytime Sleepiness and REM Sleep Behavior Disorders in Parkinson's Disease: A Narrative Review on Early Intervention With Implications to Neuroprotection 

      Gjerstad, Michaela D; Alves, Guido Werner; Maple-Grødem, Jodi (Journal article; Peer reviewed, 2018-11)
      Sleep contributes to the consolidation of our memory and facilitates learning. Short term sleep deprivation temporarily reduces mnestic capacity, whereas long lasting sleep deprivation is associated with structural changes ...
    • Genetic risk of Parkinson disease and progression: An analysis of 13 longitudinal cohorts

    • Molecular Characterization of the Plastid-localized ABC Protein TAP1 in Arabidopsis thaliana 

      Hempel, Jan Johansen (PhD thesis UiS;375, Doctoral thesis, 2018-01)
      The two TAP-like genes, AtTAP1 and AtTAP2, belong to the ABC transporter superfamily of Arabidopsis. AtTAP2/ALS1 has been shown to be important for aluminum metabolism and tolerance, however, little is known about the ...
