Dominant mutations in Arl3, linked to inherited retinal dystrophy, disrupt the active Arl3-GTP ciliary gradient and cause a defect in rod photoreceptor nuclear migration that can be rescued by elevating ciliary Arl3 activity or reducing aberrant non-ciliary Arl3 activity.
Trafficking of optogenetic tools to primary cilia using nanobodies allows to study cAMP signaling with spatial and temporal resolution independent of the cell body.
Caged, photoactivatible sphingosine localized to mitochondria permits demonstration of the importance of subcellular localization on lipid metabolism and signaling.
Asymmetric cell division is linked to cell-specific transcription by handoff of a key developmental regulator from the cytokinetic machinery to the adjacent cell pole where it oligomerizes to become stabilized and activated.
