Crumbs turns the corner
rumbs (Crb) helps flies distinguish apical from basal in their epithelia. Now two new studies show that it is required for cell expansion independently of its specification of apical polarity. During cell expansion, the apical domain of photoreceptors elongates perpendicular to the apical–basal axis so that the domain can extend from the top to the bottom of the fly eye. The process may be cons...

متن کاملPosterolateral Corner of the Knee:Current Concepts
Injuries to the posterolateral corner (PLC) comprise a significant portion of knee ligament injuries. A high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. Moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. In this sense, stress radiographs can ...
متن کاملCell polarity: Nailing Crumbs to the scaffold
Recent studies suggest that the cytoplasmic tail of the Crumbs protein establishes membrane territories in polarised epithelial cells by stabilising a PDZ-domain protein complex. The isolation of a human Crumbs homologue required for normal vision revives questions about the role of Crumbs in cell-cell interactions.
متن کاملStardust, the Janus-faced partner of Crumbs
The Drosophila melanogaster scaffolding protein Stardust (Sdt) stabilizes the transmembrane protein Crumbs, a conserved regulator of apical-basal epithelial polarity. In this issue, Perez-Mockus et al. (2017. J. Cell Biol https://doi.org/10.1083/jcb.201611196) report that a subset of Sdt isoforms are targeted by the ubiquitin ligase Neuralized, thus fine tuning the endocytosis and activity of t...
