  • Function
    The elongation of primed DNA templates by DNA polymerase delta and epsilon requires the action of the accessory proteins PCNA and activator 1. This subunit binds to the primer-template junction. Binds the PO-B transcription element as well as other GA rich DNA sequences. Could play a role in DNA transcription regulation as well as DNA replication and/or repair. Can bind single- or double-stranded DNA.
    Interacts with C-terminus of PCNA. 5' phosphate residue is required for binding of the N-terminal DNA-binding domain to duplex DNA, suggesting a role in recognition of non-primer template DNA structures during replication and/or repair.
  • Tissue specificity
    Wide tissue distribution. Undetectable in placental tissue.
  • Sequence similarities
    Belongs to the activator 1 large subunit family.
    Contains 1 BRCT domain.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
