Abstract

Every minute, several million protein and RNA molecules must be transported between the cytoplasm and the nucleus of a eukaryotic cell. The characterization of mediators, receptors and accessory factors for different nuclear import and export pathways has provided a glimpse at the molecular machinery that is responsible for these trafficking events. It appears that both inbound and outbound traffic is mediated by a protein family of related transport factors that can be classified as importins and exportins.
