A Novel Method to Visualize Active Small GTPases Unveils Distinct Sites of Sar1 Activation During Collagen Secretion.

The paper introduces SAIYAN, a method to detect small GTPase activation, revealing Sar1 activation at ER exit sites and ERGIC during collagen secretion.

Deceleration of cell cycle underpins a switch from proliferative- to terminal division in plant stomatal lineage

The paper identifies SMR4 as a cyclin-dependent kinase inhibitor that decelerates the cell cycle during the transition from asymmetric to symmetric divisions in plant stomatal lineage.
