An insulin-Myc feed-forward loop triggered by transient JNK boosts transcription of genes essential for mitochondrial respiration and biogenesis during early oogenesis to support massive mtDNA replication and inheritance in Drosophila.
The convergent evolution of yeast Mim1/2 and trypanosomal pATOM36 enable the first demonstration of reciprocal functional rescue of two evolutionary unrelated mitochondrial biogenesis complexes belonging to two different eukaryotic supergroups.
The optimal macronutrient composition, macronutrient space, varies strongly between closely related species and is determined by genetic changes in regulatory genes that globally reprogram gene expression profiles of metabolic pathways.
Two GAP proteins bound to mitochondria regulate the enyzme Rab7, and thereby the expansion of the isolation membrane during mitophagy, downstream of PINK1 and Parkin, two proteins that are mutated in familial Parkinson's disease.
Two newly identified assembly factors for the ribosome-associated iron-sulfur protein Rli1 reveal a general mechanism for how the cytosolic iron-sulfur protein assembly (CIA) machinery recruits apoproteins.
