Abstract

All right now From flies to humans, the left and right side of the body plan differs. Exactly how symmetry is broken in the early embryo is a mystery. But now two groups working independently report a genetic defect in the fly that may help uncover the mechanism. Both groups studied a mutant with reversed looping of the viscera, and discovered that the mutation lies in an unconventional myosin. Myosin directs right-handed looping and represses the default left-handed fate. This discovery now links actin-based molecular motors and the actin cytoskeleton to left–right patterning in vertebrates.
