sentence: We observed that , upon inhibition of CRM1 with LMB , the pre40S-No1 particles that are pulled down by endogenous ENP1-GFP lose their preferential enrichment in the SN3 extracts and become heterogeneously distributed between the SN3 and the SN2 fractions ( Fig. 2e , compare the interaction of ENP1-GFP with NOC4L and RRP12 in lanes 11 – 12 and 15 – 16 ) .
