Tryptophan is hydrophobic, bulky, and the rarest amino acid found in nutrients. Accordingly, the import machinery can be specialized evolutionarily. Our previous study in Saccharomyces cerevisiae demonstrated that tryptophan import by the high-affinity tryptophan permease Tat2 is accompanied by a large volume increase during substrate import.

Background: Serine/arginine (SR) protein-specific kinases (SRPKs) are conserved in a wide range of organisms, from humans to yeast. Studies showed that SRPKs can regulate the nuclear import of SR proteins in cytoplasm, and regulate the sub-localization of SR proteins in the nucleus. But no nuclear localization signal (NLS) of SRPKs was found.
