Motors: unleashing mitochondria.
Mitochondria can move along and interact with actin, yet the identity of the protein(s) mediating the interactions in metazoans is unknown. A new study reveals that a novel unconventional myosin, Myo19, is a mitochondria-associated motor that may play a role in either the transport or tethering of this organelle.
