Proteins in the Karyopherinβ family mediate the majority of macromolecular transport between the nucleus and the cytoplasm. Eleven of the 19 known human Karyopherinβs and 10 of the 14 S. cerevisiae Karyopherinβs mediate nuclear import through recognition of nuclear localization signals or NLSs in their cargos. This receptor-mediated process is essential to cellular viability as proteins are translated in the cytoplasm but many have functional roles in the nucleus. Many known Karyopherinβ-cargo interactions were discovered through studies of the individual cargos rather than the karyopherins, and this information is thus widely scattered in the literature. We consolidate information about cargos that are directly recognized by import-Karyopherinβs and review common characteristics or lack thereof among cargos of different import pathways. Knowledge of Karyopherinβ-cargo interactions is also critical for the development of nuclear import inhibitors and the understanding of their mechanisms of inhibition.
