Nanoscale architect: Illuminating the key organizer of the fruit fly's sensory world

Mechanosensory neurons utilize specialized compartments called mechanosensory organelles (MOs) to process external forces, yet the MO organization mechanisms remained unclear. In this issue, Song et al. (2023. J. Cell Biol.https://doi.org/10.1083/jcb.202209116) discovered that a microtubule-binding protein, DCX-EMAP, is the key organizer of fly MOs.
