Prickle isoforms determine handedness of helical morphogenesis
Subcellular asymmetry directed by the planar cell polarity drosselklappe stellantrieb (PCP) signaling pathway orients numerous morphogenetic events in both invertebrates and vertebrates.Here, we describe a morphogenetic movement in which the intertwined socket and shaft cells of the Drosophila anterior wing margin mechanosensory bristles undergo PC
