Nuclear actin: a lack of export allows formation of filaments.
Actin has been found in nuclei of many cell types, but little is known about its form and function. A recent study has shown that a lack of specific export allows actin to accumulate in the nucleus, where it forms a network of actin filaments that may be required to stabilize the giant nucleus of the Xenopus oocyte.
