Charcot-Marie-Tooth disease (CMT) is the most common inherited neuropathy in humans, linked to mutations in dozens of different genes. Two of these genes encode the proteins GDAP1 and NDRG1. We have solved the crystal structures of these two proteins, in order to better understand their structure, function, and involvement in disease.
Myelin, the insulative multilamellar sheath that enwraps axons, speeds up our nerve impulses by two orders of magnitude – a prerequisite for an efficient nervous system that we humans and other vertebrates enjoy. Myelin gains its structure and function from a high abundance of lipids and proteins, many of which are specific to this enigmatic biological system.
An important European-funded initiative has been launched to explore how common molecular mechanisms may link metabolic disorders, especially type 2 diabetes and obesity, with brain disorders such as Alzheimer's disease, obsessive-compulsive disorder, and autism spectrum disorders. Jan Haavik and Aurora Martinez from the Department of Biomedicine are the norwegian participants.
Researchers at the University of Bergen looked if there is a connection between the mode of delivery and the genetics of children’s intelligence.
Attention-deficit/hyperactivity disorder and autoimmune diseases: etiological relationships and therapeutic possibilities
Arc er et protein som er gjerne omtalt som hukommelsens hovedregulator. Det har likhet med noen virusproteiner, og kan danne virus-lignende capsid partikkler. Vi har lykket til å oppløse den tredimensjonale strukturen for første gang.
The Shank family of proteins functions as a molecular scaffold in the neuronal post-synaptic density, enabling numerous protein-protein interactions. Shanks are large multi-domain molecules, and one of the conserved domains is an SH3 domain. Using high-resolution X-ray crystallography, we show that the SH3 domain in the Shank family has lost its canonical ligand-binding site.
The molecular processes of myelin maturation are to a large extent still unknown. A coordinated interplay between regulatory and functional molecules must take place for correct timing of myelin membrane apposition and compaction, such that cytoplasmic channels are also formed in a correct way.
Professor Jan Haavik has been given the Helse Vest Research award 2016 for his research on discovering biological mechanisms that can cause ADHD-symptoms. He was rewarded the prize during the annual research conference of Helse Vest.
