In genetic screens for ribosomal export mutants, we identified CFD1, NBP35 and NAR1 as factors involved in ribosome biogenesis. Notably, these components were recently reported to function in extramitochondrial iron-sulfur (Fe-S) cluster biosynthesis. In particular, Nar1 was implicated to generate the Fe-S clusters within Rli1, a potential substrate protein of unknown function. We tested whether the Fe-S protein Rli1 functions in ribosome formation. We report that rli1 mutants are impaired in pre-rRNA processing and defective in the export of both ribosomal subunits. In addition, Rli1p is associated with both pre-40S particles and mature 40S subunits, and with the eIF3 translation initiation factor complex. Our data reveal an unexpected link between ribosome biogenesis and the biosynthetic pathway of cytoplasmic Fe-S proteins.
