The E3 ubiquitin ligase complex linear ubiquitin chain assembly complex (LUBAC) forms a branched chain on linear ubiquitin chains depending on the RING-in-between-RING-type E3 ligase heme-oxidized IRP2 ubiquitin ligase 1 (HOIL-1L).

Bioinformatic and biochemical studies provide evidence that covalently bound flavins are common and participate in wide-ranging extracytosolic redox activities throughout bacterial life.

Across a physiological span of ATP-free energy, leukemic mitochondria primarily consume, rather than produce, ATP.

Protein aggregates resulting from mutations in C9orf72 impair different aspects of cellular quality control in the cytosol and the nucleus, but mRNA-mediated effects contribute more strongly to toxicity.

Structure-guided biochemistry defines how the coupling between nucleic acid substrate binding and ATPase activity is used by a molecular switch to load ring-shaped motor proteins onto single-stranded DNA.

Two proteins called Sec17 and Sec18 may have a larger role in membrane fusion than is commonly assumed in textbook models.

Activation of the sarcoplasmic reticulum calcium pump and enhancement of cellular calcium homeostasis by dwarf open reading frame reveal how this small membrane protein opposes phospholamban inhibitory function in cardiac muscle.

An immunofluorescent analysis of 465 protein kinases revealed a substantial role of liquid-liquid phase separation in kinase localization and identified new kinase localizations to mitochondria and other organelles.

Hoxa3 and Hoxa11 translation inhibitory elements block cap-dependent translation by using upstream open reading frames with distinct modes of action.

Analysis of neo-splicetope-specific T cell responses strongly questions the idea that in vitro proteasome-catalyzed peptide splicing reaction simulates the in vivo situation with the same high fidelity as the in vitro generation of non-spliced epitopes.
