BETA IMPORTINS -
Importin-β family proteins are nucleocytoplasmic transport receptors that import and export proteins and RNAs through the nuclear pores. In some import/export pathways, importin-β directly interacts with the cargo. For cargo containing a classical nuclear localization (cNLS) signal, importin-α acts as an adaptor linking the cargo to importin-β. (Adapted from FBrf0235243, FBrf0131350 and PMID:21029754).
Protein Function (UniProtKB)
Export receptor for importin alpha. Mediates importin-alpha re-export from the nucleus to the cytoplasm after import substrates have been released into the nucleoplasm (By similarity).

          Renamed from 'Cas' to 'Cse1' in order to minimise confusion with the unrelated 'cas' gene (which only differed by case) and to be consistent with the nomenclature used in other organisms for orthologs of this gene.

          Other Comments

          S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.

          (Stroschein-Stevenson et al., 2006)

          Cas is a ubiquitous export receptor that seems to be required in all tissues.
