Abstract

Nucleolar protein 9 (NOP9) is an RNA-binding nucleolar protein found in yeast and required for pre-rRNA processing. It is a component of both the 90S pre-ribosome and the pre-40S ribosome [ 1 ]. This entry also includes APUM23 from Arabidopsis. APUM23 is a nucleolar PUF protein involved in pre-rRNA processing [ 2 ].
