   Sammanfattning : The kidney is one of the most important and complex organs in the humanbody with the task of filtering hundreds of litres of blood daily. It is responsiblefor the salt and acid/base balance in the body, as well as secretinghormones important for red blood cell production and blood pressure regulation. LÄS MER

   Sammanfattning : Apoptosis is one of the most common types of cell death. Under physiological conditions, it plays an essential role in removal of damaged and potentially harmful cells. Excessive apoptosis has however been linked to a number of diseases including proteinuric kidney disease and DKD, and is believed to enhance the disease progression. LÄS MER

5. 24. Characterization of membrane protein active transport under native-like conditions

   Författare :Harsha Ravishankar; Magnus Andersson; Pål Stenmark; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological Physics; Biologisk fysik;

   Sammanfattning : P-type ATPase proteins are a family of membrane proteins that maintain concentration gradients of e.g. ions by ATP-driven transport across the membrane. While these transporters share many features in their molecular architecture, structural differences are required to convey ion specificity. LÄS MER

7. 25. Computational Study of Calmodulin’s Ca2+-dependent Conformational Ensembles

   Författare :Annie M. Westerlund; Erik Lindahl; Lucie Delemotte; Björn Wallner; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; Calmodulin; Free energy estimation; Gaussian mixture models; Spectral clustering; conformational selection; Biological Physics; Biologisk fysik;

   Sammanfattning : Ca2+ and calmodulin play important roles in many physiologically crucial pathways. The conformational landscape of calmodulin is intriguing. Conformational changes allow for binding target-proteins, while binding Ca2+ yields population shifts within the landscape. Thus, target-proteins become Ca2+-sensitive upon calmodulin binding. LÄS MER
