Internally tagged, functional Cse4/CENP-A/CenH3 histone variant is exclusively centromeric and stable through the budding yeast cell cycle after replacement in S phase.
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 xc- and induce ER stress, suggesting these may be useful tools for probing the functions of system xc- 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.
