PodJL provides the positional information for the localization of several polar organelles (pili, adhesive holdfast and chemotactic apparatus) by recruiting structural (CpaE) and regulatory (PleC) proteins to a specific cell pole. Both PodJL and PodJS localize to the swarmer pole at different stages of the cell division. PodJS, from the previous progeny, accumulates in the swarmer cell, and is partially degraded during the swarmer-to-stalked transition by sequential proteolytic cleavages (MmpA). PodJL, from the new progeny, is synthesized in the early predivisional cell, and then is likely to be converted to PodJS by proteolytic cleavage of periplasmic domain. After cell division, PodJL disappears, while the level of PodJS increases in the swarmer cell progeny. Two isoforms exist, the full-length translation product PodJL and a C-terminal truncated form PodJS. Both appear during a specific time period of the cell cycle to control different aspects of polar organelle development. PodJS must be degraded to preserve the asymmetry of the next cell cycle.
