Function:Part of a multiprotein post-splicing mRNP complex involved in both mRNA nuclear export and mRNA surveillance. Involved in nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. Binds spliced mRNA upstream of exon-exon junctions.,similarity:Belongs to the RENT3 family.,subcellular location:Shuttling between the nucleus and the cytoplasm.,subunit:Found in a mRNP complex with RENT1, RENT2, RENT3A and RENT3B. Found in a mRNP complex with SMG1, RENT3A, RENT3B, RBM8A, THOC4 and NXF1. Found in a post-splicing complex with NXF1, RBM8A, RENT1, RENT2, RENT3A, RENT3B and RNPS1. Interacts with RENT2.,tissue specificity:Isoform 1 is strongly expressed in testis, uterus, muscle, fetal brain and spinal cord. Isoform 2 is strongly expressed in fetal brain and spinal cord.,
