NRDE2 Interacts with an Early Transcription Elongation Complex and Widely Impacts Gene Expression.

ABSTRACT: NRDE2 is a highly conserved protein implicated in post-transcriptional gene silencing in Schizosaccharomyces pombe and Caenorhabditis elegans and has been shown to modulate splicing in mammals. To explore whether NRDE2 participates in additional processes in human cells, we performed tandem affinity purification followed by proteomic analysis of NRDE2 from nuclear extracts of HEK293T and HeLa cells. Our analysis confirmed the interaction of NRDE2 with its well-characterized partner, the MTR4 helicase (MTREX), as well as with multiple splicing factors. Notably, we also identified interactions with chromatin-associated proteins involved in transcription, including the Polymerase-Associated Factor 1 (PAF1) complex and elongating forms of RNA polymerase II (RNAPII).
