Biochemical and genetic approaches revealed a posttranslational mechanism controlling the abundance of SUN2, a critical nuclear envelope protein.

Locally activatable bioluminescence (LABL) is a genetically encoded reporter that allows real time, in vivo measurement of distinct clocks in different cells and tissues in Drosophila.

The anchoring properties of Ca_V β2 subunits to the plasma membrane determine the biophysical states of Ca_V2.2 channels by regulating PIP₂ coupling to the nonspecific phospholipid-binding site in the I–II loop.

Animal models reveal that mitochondrial complex I is dispensable for homeostatic functions of the mouse liver.

High-throughput analysis of several Saccharomyces cerevisiae contact sites reveals a large data set of potential contact site proteins, including proteins involved in the regulation of lipid distribution within cells.

All the characteristic traits of the eukaryotic cell, the basic unit of all macroscopic life, commenced to originate in a prokaryote as means to serve an endosymbiont today known as mitochondria.

Coarse-grained modeling of mammalian kinetochore-fiber shapes generated under microneedle manipulation reveals the need for lateral anchorage 1-3 μm from the kinetochore to robustly preserve their orientation in the spindle center, promoting mechanical integrity in the dynamic spindle.

Mitochondrial Cx43 hemichannels regulate ATP generation by mediating K+, H+, and ATP transfer across the mitochondrial inner membrane and the interaction with mitochondrial ATP synthase, contributing to maintenance of mitochondrial redox and cell protection under oxidative stress.

Substrate recognition by a receptor protein tyrosine phosphatase is mediated by binding to its pseudophosphatase domain via a short helix that is >100 amino acids distant from the target phosphosite, uncovering principles of phosphatase substrate recognition and potential scaffolding functions.

STED microscopy of human mitotic spindles reveals how augmin-nucleated microtubules protect the cell from erroneous kinetochore-microtubule attachments and ensure a highly organized architecture of the spindle required for mitotic fidelity.
