Activation mechanism of class A GPCRs: machine learninganalysis of experimental structural databases

Santeri Elias Paajanen, Felix Eurasto, Waldemar Kulig…·Ilpo Vattulainen

This study uses machine learning to analyze structural data of class A GPCRs, revealing that ligand binding follows conformational selection while G protein binding stabilizes the active state.

Control of Golgi- V-ATPase through Sac1-dependent co-regulation of PI(4)P and cholesterol

Xin Zhou, Miesje M. van der Stoel, Shreyas Kaptan…·Elina Ikonen

This study shows that Sac1 regulates Golgi V-ATPase assembly by controlling TGN membrane composition through lipid exchange, leading to Golgi fragmentation and impaired glycosylation.
