    Summary
    Enables nuclear localization sequence binding activity. Involved in NLS-bearing protein import into nucleus and spermatogenesis. Predicted to be located in cytoplasm. Predicted to be active in nucleoplasm. Is expressed in adult head and organism. Orthologous to several human genes including KPNA1 (karyopherin subunit alpha 1) and KPNA6 (karyopherin subunit alpha 6). [provided by Alliance of Genome Resources, Dec 2024]

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. This study identified a potential nuclear localization signal at the N-terminal end of Yorkie as well as a critical role for Importin alpha 1 in Yorkie nuclear import.
      Title: Importin α1 Mediates Yorkie Nuclear Import via an N-terminal Non-canonical Nuclear Localization Signal.
    2. This is supported by attenuated interaction of IMPa1 with TIM carrying a mutation previously shown to prevent nuclear entry of TIM and PER.
      Title: Drosophila TIM binds importin α1, and acts as an adapter to transport PER to the nucleus.
    3. Drosophila alpha1 performs paralog-specific activities that are essential for gametogenesis and regulation of subcellular alpha1 localization may affect cell fate decisions.
      Title: Drosophila importin alpha1 performs paralog-specific functions essential for gametogenesis.
    4. each Imp-alpha protein carries during Drosophila spermatogenesis distinct, albeit overlapping, functions that may involve nuclear import of proteins, microtubule organisation, and other yet unknown processes
