The novel role of hepcidin in cell-autonomous iron regulation changes our understanding of tissue-specific iron control, and of its interplay with systemic iron homeostasis.

Eukaryotic translation initiation factor 3 (eIF3) is required to stabilize the binding of mRNA at the exit channel of the small ribosomal subunit and acts at the entry channel to accelerate mRNA recruitment to the translation preinitiation complex.
Autophagic cargo receptors recruit the E3-like enzyme for Atg8 lipid conjugation to the cargo and thereby promote local formation of Atg8-positive autophagosomal membranes.
Lamellar and tubular cristae in mitochondria form by two different molecular pathways that form both involve F1FO-ATP synthase dimers and the MICOS complex, but formation of lamellar cristae also relies on Mgm1/Opa1.
The polyQ tract of pathogenic Huntingtin causes aggregation when expanded in Huntington’s disease, but its two flanking domains control its conformational landscape, proteostasis and neurotoxicity.
An empirically derived scoring system for identifying optimal communication modules of aptazymes accelerates the development of ligand-responsive RNA genetic switches functional in mammalian cells.

SPRTN is a protease essential for the repair of cytotoxic DNA-protein cross links and this function is defective in patients afflicted with Ruijs-Aalfs syndrome -a segmental progeroid syndrome.
