biosights: September 7, 2009

The contractile vacuole is an osmoregulatory organelle in protozoans that expels excess water from the cytosol through a complex sequence of membrane movements. A new study identifies a myosin motor protein that orchestrates these movements in Dictyostelia. This biosights episode presents the paper by Jung et al. from the August 24th, 2009 issue of the Journal of Cell Biology, and includes an interview with senior author John Hammer III.
