The genes in the screen were named hgcA through hgcG ("high GC"). The HgcE has been renamed as Pf3 and identified as an H/ACA snoRNA that is suggested to target 23S rRNA for pseudouridylation.
The genes on the screen were labeled hgcA through hgcG, denoting "high GC". The previously known HgcE has been rechristened Pf3 and recognized as an H/ACA snoRNA that is thought to target 23S rRNA for pseudouridylation.
