PAIP1 couples mRNA export to cytoplasmic mRNP remodeling and poly(A) homeostasis
Messenger ribonucleoproteins (mRNPs) acquire distinct protein compositions as they move from the nucleus to the cytoplasm, yet how this transition is coordinated and how inefficient remodeling affects downstream mRNA metabolism remains poorly understood. Here, we identify PAIP1 as a metazoan cofactor of the mRNA export...
