Abstract

A subset of messenger RNAs (mRNAs) that contain inverted Alu elements in their 3′ untranslated region are inefficiently exported to the cytoplasm and retained in subnuclear bodies called paraspeckles. The arginine methyltransferase CARM1 (coactivator-associated arginine methyltransferase 1) promotes the nuclear export of these mRNAs by methylating the paraspeckle component p54nrb, which reduces the binding of p54nrb to the inverted Alu elements, and down-regulating synthesis of another paraspeckle component, the long noncoding RNA NEAT1, which inhibits paraspeckle formation.
