Domain

rRNA-processing arch domain (IPR025696)

Short name: rRNA_proc-arch_dom

Domain relationships

None.

Description

The essential RNA helicase Mtr4 is an exosome-activating cofactor. This arch domain is carried in Mtr4 and Ski2 (the cytosolic homologue of Mtr4). The arch domain is required for proper 5.8S rRNA processing, and appears to function independently of canonical helicase activity [PMID: 20512111].
