Acrosomal actin: twists and turns of a versatile filament.
A new electron cryomicroscopic reconstruction of an actin-scruin bundle from Limulus sperm reveals details about the enormous structural plasticity within F-actin. The twist and tilt of the actin subunits show very large deviations from ideal F-actin, providing clues about actin dynamics.
