  • Function

    Essential component of the apolipoprotein B mRNA editing enzyme complex which is responsible for the postranscriptional editing of a CAA codon for Gln to a UAA codon for stop in APOB mRNA. Binds to APOB mRNA and is probably responsible for docking the catalytic subunit, APOBEC1, to the mRNA to allow it to deaminate its target cytosine. The complex also protects the edited APOB mRNA from nonsense-mediated decay.
  • Tissue specificity

    Widely expressed with highest levels in brain, liver, pancreas, colon and spleen.
  • Sequence similarities

    Contains 3 RRM (RNA recognition motif) domains.
  • Domain

    The RRM domains are necessary but not sufficient for binding to APOB mRNA. Additional residues in the pre-RRM and C-terminal regions are required for RNA-binding and for complementing APOBEC1 activity.
  • Cellular localization

    Nucleus. Endoplasmic reticulum. Cytoplasm. Predominantly nuclear where it localizes to heterochromatin. Also cytoplasmic where it is found at the outer surface of the endoplasmic reticulum (By similarity). Shuttles between the nucleus and cytoplasm. May be transported into the nucleus by the nuclear import protein TNPO2/TRN2 or by APOBEC1.
