The cAMP-dependent protein kinase A controls the switch from actively sprouting new blood vessel formation to vessel quiescence by reducing endothelial autophagy through phosphorylation-mediated destabilisation of ATG16L1.
Grid cells lose their hexagonality during hippocampal inactivation, but maintain temporal and spatial synchrony between pairs of cells, implying that hippocampus does not determine phase relations between grid cells.
The histone modification H3K9me2 marks peripheral heterochromatin and ensures positional information is safeguarded through cell division such that individual lamina-associated domains are re-established at the nuclear periphery in daughter nuclei.
A genetic screen in a unicellular photosynthetic organism uncovers the first essential signaling component in the chloroplast unfolded protein response that relays information from the chloroplast to the nuclear compartment.
Proximity-labeling using engineered biotin ligases TurboID and miniTurbo enables detection of cell-type-specific and low abundance protein complexes and subcellular proteomes in Arabidopsis and other plants.
