Microtubule motors: LSD2 trips the toggle.
The Perilipin homologue LSD2 has been identified as a regulator of microtubule motor activity in Drosophila embryos. LSD2 is required for the net directional transport of lipid droplets and the new data support a model in which the protein imparts bias onto a molecular toggle that otherwise randomly engages minus and plus end motors in a paired set.[1]References
