  • Function

    Required for DNA replication, normal cell cycle progression and cell proliferation. Forms a cytoplasmic complex with HSP90 and H1 linker histones and stimulates HSP90 ATPase activity. NASP and H1 histone are subsequently released from the complex and translocate to the nucleus where the histone is released for binding to DNA.
  • Tissue specificity

    Isoform 1 is testis- and sperm-specific.
  • Sequence similarities

    Belongs to the NASP family.
    Contains 3 TPR repeats.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Cytoplasm. Nucleus.
