Mutational analysis and biochemical experiments suggest that the conserved β-hairpin-like membrane-reentrant loop of RseP - an S2P family intramembrane cleaving protease - helps to discriminate substrates by directly interacting with their transmembrane segments.
The modularity and unequivocal input/response of Notch signaling are harnessed to measure cell-surface shedding of diverse transmembrane receptors to identify new proteolytic switches and detect modulation of proteolysis by therapeutics.
Skd3 (human ClpB) is a potent ATP-dependent mitochondrial protein disaggregase that is activated by the rhomboid protease, PARL, and inactivated by MGCA7-linked mutations.
The conserved polypeptide transport associated (POTRA) domains of the protein import channel, Toc75, are essential for protein import into chloroplasts.
Super-resolution microscopy sets a new strategy to comprehend the membrane organization of γ-secretase at single complex resolution identifying nanodomain associations and its diffusion in situ in the living membrane.
Live-cell nanometer-resolution RNA labeling method enables transcriptome-wide mapping of endogenous RNAs in nuclear, cytosol, ER, and mitochondrial subcompartments.
