Ran GTPase: a master regulator of nuclear structure and function during the eukaryotic cell division cycle?

abstract：:Endosomal protein sorting governs the fate of many physiologically important proteins involved in a panoply of cellular functions. Recent discoveries have revealed a vital role for endosomally localised branched actin patches in facilitating protein sorting. The formation of the actin patches has been shown to require...
