MTR4, a putative RNA helicase and exosome co-factor, is required for proper rRNA biogenesis and development in Arabidopsis thaliana.

The Plant journal : for cell and molecular biology - 1 Oct 2011

Lange Heike, Sement François M, Gagliardi Dominique

Abstract excerpt

The exosome is a conserved protein complex that is responsible for essential 3'→5' RNA degradation in both the nucleus and the cytosol. It is composed of a nine-subunit core complex to which co-factors confer both RNA substrate recognition and ribonucleolytic activities. Very few exosome co-factors have been identified in plants. Here, we have characterized a putative RNA helicase, AtMTR4, that is involved in the...
