Researchers reveal new details of crucial steps involved in the maturation of ribosomes

Ribosomes synthesize all the proteins in cells. Studies mainly done on yeast have revealed much about how ribosomes are put together, but an Ludwig-Maximilians-Universitaet (LMU) in Munich team now reports that ribosome assembly in human cells requires factors that have no counterparts in simpler model organisms.

Researchers reveal identity of the last unknown protein of autophagy

Drs. Nobuo Noda (Director) and Kazuaki Matoba (Senior Researcher) et al. at the Institute of Microbial Chemistry (BIKAKEN, Tokyo, Japan) discovered that Atg9, one of the proteins that function to mediate autophagy, has phospholipid-translocation activity (the lipid scramblase activity) between the two layers of the lipid bilayer and elucidated that the protein's activity brings about autophagosome membrane expansion.
