Professor Poul Nissen awarded the Anders Jahre medical prize 2021

One of Scandinavia’s most prestigious research honours, the Anders Jahre Medical Prize, has been conferred on Professor Poul Nissen of Aarhus University. The prize has been awarded in recognition of Professor Nissen’s groundbreaking research on the structure and function of membrane proteins. His work has advanced our understanding of a variety of…

Binding site I of SERCA is not conserved in LMCA1. Alignment between LMCA1 G4 E2-BeF3- (red) and SERCA E2-AlF4- (pdb: 3b9r) (dark grey). Relevant Ca2+-coordinating residues are shown as sticks. The structures are aligned by the residues shown as sticks. SERCA Ca2+ binding site I and II are indicated. Figure: Sara Basse Hansen.

Ion and lipid transporters specialize for their niche

Cell viability require that a variety of functions at the cell membrane are maintained properly. P-type ATPases translocate substrates across the membrane, and they have evolved into different types taking care of specific substrates within a diverse range. Now, key structural aspects have been described on how two different types of P-type…

Overview of some of the RNA origami structures designed in the current study compared with a bacterial ribosome (grey). RNA origami structures are coloured by the elements they consist of: 180 degree interactions (purple), 120 degree interactions (dark green), tetra loops (yellow) and dovetail seams (dark blue). Central structure scaffold aptamers (green and orange) and fluorescent proteins. Figure: Cody Geary and Ebbe S. Andersen.
Design and characterisation of RNA origami structures. RNA drawings, atomic models and sequences are designed on the computer. A DNA template is synthesised and transcribed and then folded by an RNA polymerase. The RNA structure is characterised by microscopy methods. Figure: Cody Geary

Bigger and better RNA scaffolds for organising proteins

Researchers from Aarhus University and Caltech have developed a method to build much larger, though still nanosize, RNA scaffolds than previously thought possible using RNA origami. The method is based on new software that has been made available online so other researchers can use it to develop biosensors, nanorobots and medicine – including…
