The position of organelles within cells is highly regulated, but the factors that control positioning are not well understood. Starr and Han (p. 406) examined the process of positioning the nucleus in Caenorhabditis elegans embryos and discovered that a protein termed ANC-1, in association with another protein, UNC-84, was important. ANC-1 appears to act by tethering nuclei to the cell's actin cytoskeleton through its interaction with cytoplasmic actin and UNC-84 on the nuclear envelope.
