miR-142 is instrumental for actin homeostasis, and its loss disrupts the cytoskeleton organization and thrombopoiesis of megakaryocytes.

In vitro, in vivo and in silico evidence suggests that bacteria exploit intrinsic chromosomal fluctuations to achieve intracellular transport.

Maternal embryonic leucine zipper kinase (MELK) is a new anti-cancer target that is highly selective for basal-like breast cancer.

A cross-linking screen finds proteins that interact with TANGO1 to export Procollagen VII, and suggests a new model for the secretion of these bulky cargoes that are involved in skin and bone formation.

Sec1/Munc18 (SM) proteins shield SNARE complexes from NSF/Sec18-mediated disassembly through cooperative binding interactions with SNARE complexes and the universal co-chaperone α-SNAP/Sec17.

Erastin and sorafenib inhibit system x_c^- and induce ER stress, suggesting these may be useful tools for probing the functions of system x_c^- and its role in inducing ER stress and ferroptosis.

In addition to its cytoplasmic role for translation, the seryl-tRNA synthetase also antagonizes the c-Myc transcription factor in the nucleus to transcriptionally repress the growth factor VEGFA and ensure proper development of the vasculature in vertebrates.

A systematic comparison of experimentally measured and theoretically predicted magnitudes of organelle abundance fluctuations suggests that budding yeast produces the maximum level of variability in organelle abundance that can be generated by organelle biogenesis pathways.
