Photosynthesis takes place in specialized membrane systems, made up of stacked disks linked together by unstacked planar leaflets. An LMU team has now identified a protein that tucks the membrane in at the edge of each stack. By making use of sunlight to generate molecular oxygen and other energy-rich chemical compounds that other organisms can utilize as nutrients, photosynthesis provides the basis for almost all life on Earth. Radiant energy from the Sun is captured by pigment-protein...

The research group of Professor Pekka Lappalainen at the Institute of Biotechnology, University of Helsinki, has identified a previously unknown mechanism which modifies the structure of plasma membranes in intestinal epithelial cells. Unlike other proteins with a similar function, the new protein "“ named 'Pinkbar' by the researchers - creates planar membrane sheets. Further research investigates the potential connection of this protein with various intestinal disorders. The study was...

By Churchward, Matthew A Rogasevskaia, Tatiana; Brandman, David M; Khosravani, Houman; Nava, Phillip; Atkinson, Jeffrey K; Coorssen, Jens R ABSTRACT The Ca^sup 2+^-triggered merger of two apposed membranes is the defining step of regulated exocytosis. CHOL is required at critical levels in secretory vesicle membranes to enable efficient, native membrane fusion: CHOL-sphingomyelin enriched microdomains organize the site and regulate fusion efficiency, and CHOL directly supports the capacity...
