  • Function
    Component of the cleavage factor Im complex (CFIm) that plays a key role in pre-mRNA 3'-processing. Involved in association with NUDT21/CPSF5 in pre-MRNA 3'-end poly(A) site cleavage and poly(A) addition. CPSF6 binds to cleavage and polyadenylation RNA substrates and promotes RNA looping.
  • Sequence similarities
    Belongs to the RRM CPSF6/7 family.
    Contains 1 RRM (RNA recognition motif) domain.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization
    Nucleus. In punctate subnuclear structures localized adjacent to nuclear speckles, called paraspeckles.
