Multicolor 3D MINFLUX nanoscopy of mitochondrial MICOS proteins

Authors Pape JK, Stephan T, Balzarotti F, Büchner R, Lange F, Riedel D, Jakobs S, Hell SW Journal Proceedings of the National Academy of Sciences Citation PNAS, Aug 2020, 202009364. Abstract The mitochondrial contact site and cristae organizing system (MICOS) is a multisubunit protein complex that is essential for the

Multi-color 3D MINFLUX nanoscopy visualizes the cellular distribution and relative position of proteins that are only a few nanometers apart. The picture shows a mitochondrion from a human skin cell in which two proteins in the inner mitochondrial membrane are stained: A subunit of the MICOS complex (Mic60), is colored in orange, a subunit of the mitochondrial ATP synthase (ATPB), is colored in blue. The scale bar has a length of 500 nanometers. © Till Stephan & Jasmin Pape / Max Planck Institute for Biophysical Chemistry

Proteine ganz nah

In einer ersten Anwendung der leistungsstarken MINFLUX-Nanoskopietechnik in der Zellbiologie haben Forscher um Stefan Hell und Stefan Jakobs die Verteilung einzelner Proteine in einem etwa 20 Nanometer großen Proteinkomplex innerhalb eines Zellorganells mehrfarbig und dreidimensional sichtbar gemacht. Diese Technik ist damit hundertmal schärfer als die herkömmliche Fluoreszenz-Lichtmikroskopie. Die MINFLUX-Nanoskopie erweist

RAB39B is redistributed in dementia with Lewy bodies and is sequestered within aβ plaques and Lewy bodies

Authors Koss DJ, Bondarevaite O, Adams S, Leite M, Giorgini F, Attems J, Outeiro TF Journal Brain Pathology Citation Brain Pathol. 2020;10.1111/bpa.12890. Abstract Loss of function mutations within the vesicular trafficking protein Ras analogy in brain 39B (RAB39B) are associated with rare X‐linked Parkinson’s disease (PD). Physiologically, RAB39B is localized
