ATP‐dependent proteases are present in all organisms, where they are responsible for much of intracellular protein degradation. Most proteins are processively unfolded and degraded into small peptides; however, in a few so‐called slippery substrates, the protease stalls at a folded domain and releases a large protein fragment. In this review, we describe the properties of physiological slippery substrates that are processed in this manner by ATP‐dependent proteases and the recent advances that have been made in understanding the mechanism underlying their partial degradation. © 2014 IUBMB Life, 66(5):309–317, 2014
