Ubiquitin-dependent signal amplification in lipid saturation sensing

Jona Causemann, Barbara Schmidt, Daniel Granz…·Robert Ernst

The paper investigates how Mga2 converts membrane physical cues into biochemical outputs via ubiquitylation, revealing a signal amplification mechanism involving E3 ligase autoubiquitylation.

Understanding the regulation of STIM1-ORAI1 interaction using a reaction-diffusion model

Barbara Schmidt, Ivan Bogeski, Barbara A. Niemeyer, Heiko Rieger

The paper uses a reaction-diffusion model to analyze STIM1-ORAI1 interactions in CRAC channel formation, showing how ROS inhibition affects Ca2+ influx and channel configuration preferences.
