Nop53 depletion differentially affects the association of the nucleocytoplasmic AFs Arx1 and Nmd3 with pre-60S intermediates. (A) Schematic representation of the pre-rRNA processing in S. cerevisiae, highlighting the stages during which Nop53 is associated with the pre-60S and the hybridization position of the Northern blot probes. (B) The pre-rRNAs copurified (IP) with Arx1-TAP and Nmd3-TAP in biological triplicates both in Nop53 depleted (−) and non-depleted (+) conditions were assayed along with the Input (total RNA) by Northern blot using the indicated probes. The empty TAP tag was used as a negative control and the Δrrp6 strain as a control for the accumulation of 5.8S+30 pre-rRNA. *non-specific band.
