The MTR4 helicase recruits nuclear adaptors of the human RNA exosome using distinct arch-interacting motifs

Abstract

The human RNA exosome contains a nuclear co-factor MTR4, which unwinds structural RNAs and recruits adaptors for different RNA processing and decay pathways. Here the authors uncover new variations of the arch-interacting motif (AIM) in NVL and ZCCHC8 and characterise their interaction with MTR4.
